A new operating system is now available for download in the Mac App Store OS X Yosemite. Switching to it is again very simple and the whole process of installing OS X Yosemite is intuitive. It's enough download installation package from the Mac App Store and then install the new system on one of the supported Macs in a few controlled steps.
However, it may be useful to have an installation disc handy in the future, from which you can reinstall the system at any time, without having to connect to the Internet and download the file again. Such an installation disk can then be used even during a clean installation of the system. Creating an installation disc has become a bit easier in the last two years than it used to be. It is necessary to use the Terminal during the process, but only one simple code needs to be entered into it, so even a user who does not normally come into contact with the Terminal can do it.
[do action=”infobox-2″]Computers compatible with OS X Yosemite:
- iMac (Mid 2007 and newer)
- MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 and later)
- MacBook Pro (13-inch, Mid-2009 and later), (15-inch, Mid/Late 2007 and later), (17-inch, Late 2007 and later)
- MacBook Air (Late 2008 and newer)
- Mac Mini (Early 2009 and later)
- Mac Pro (Early 2008 and later)
- Xserve (Early 2009)[/to]
All the user needs to create an installation disc is a USB stick with a minimum size of 8 GB. However, it must be noted that the entire original content of the keyring will be deleted as part of the installation file creation, and it is therefore necessary to set aside a medium for this purpose that you will not need for anything else in the future.
Creating an installation disk or USB stick
To successfully create an installation disc, you must first download the new OS X Yosemite. The new operating system is available in the Mac App Store free, so there can be practically no problem when downloading it. Even after installation, there is no problem downloading the installation file with OS X Yosemite at any time, however, the entire system has a relatively large volume (around 6 GB), so it is not a good idea to save it for future use. This can be done in two ways: either you copy the installation application outside the default location in the folder /Application, from which it is automatically deleted after installing the new system, or you can create an installation disk straight away. This is necessary for a clean installation of the operating system.
If you are downloading OS X Yosemite for the first time (and you are still working on an older version of the system), a window with a wizard to install the new operating system will automatically pop up after the download is complete. Turn it off for now though.
- Connect the selected external drive or USB stick, which can be completely formatted.
- Start the Terminal application (/Applications/Utilities).
- Enter the code below in the Terminal. The code must be entered in its entirety as one line and a name Untitled, which is contained in it, you must replace with the exact name of your external drive/USB stick. (Or name the selected unit Untitled.)
...
sudo /Applications/Install OS X Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install OS X Yosemite.app --nointeraction
- After confirming the code with Enter, Terminal prompts you to enter the administrator password. Characters will not be displayed when typing for security reasons, but still type the password on the keyboard and confirm with Enter.
- After entering the password, the system will start processing the command, and messages about formatting the disk, copying the installation files, creating the installation disk and the completion of the process will pop up in the Terminal.
- If everything was successful, a drive with a label will appear on the desktop (or in the Finder). Install OS X Yosemite with the installation application.
Clean install of OS X Yosemite
The newly created installation drive is especially needed if you want to perform a clean installation of a new operating system for some reason. The process isn't particularly complicated, but you can't do it without an installation disc.
Before doing a clean install and formatting the drives, make sure to back up the entire drive (for example via Time Machine) so you don't lose any important data.
To perform a clean install, just follow these steps:
- Insert the external disk or USB stick with the OS X Yosemite installation file into the computer.
- Restart your Mac and hold the key during startup Option ⌥.
- From the offered drives, select the one on which the OS X Yosemite installation file is located.
- Before the actual installation, run Disk Utility (found in the top menu bar) to select an internal drive on your Mac and completely erase it. It is necessary that you format it as Mac OS Extended (Journaled). You can also choose the level of deletion security.
- After successfully erasing the drive, close Disk Utility and continue with the installation that will guide you.
System restore from backup
After performing a clean installation, it's up to you whether you want to completely restore your original system, pull only selected files from the backup, or start with a completely clean system.
After installing on a clean disk, OS X Yosemite will offer you an automatic recovery of the entire system from a Time Machine backup. Just connect the appropriate external drive on which the backup is located. Then you can pick up where you left off in the previous system.
However, you can skip this step and use the app later Data Transfer Wizard (Migration Wizard). You can find detailed instructions for the application <a href="https://cdn.shopify.com/s/files/1/1932/8043/files/200721_ODSTOUPENI_BEZ_UDANI_DUVODU__EN.pdf?v=1595428404" data-gt-href-en="https://en.notsofunnyany.com/">here</a>His Data transfer wizard you can manually select which files from the backup you want to transfer to the new system, for example only individual users, applications or settings.
I want to ask. Will anyone try installing Yosemite on a macbook with a Windows 8.1 partition? I would like to upgrade Maverick to Yosemite, but I am afraid of losing the Windows partition. Very important for my work. I have a macbook pro late 2012. The upgrade from Mount Lion to Maverick was no problem.
Thank you
I wouldn't worry about an update, it won't affect your bootcamp in any way, but a clean install would probably take the whole thing. But I'd also rather wait for the first responses, I'm in the same situation, W7 section, which I would very much like to lose and do again.
Thanks :) I'll wait too. And now one more stupid question. I am downloading the Yosemite installer via the mac store. If I run it and put the installation on the disk where Maverick is, is it an upgrade or a clean installation? When I installed Maverick via Lion, it was in the mac store as an upgrade :) Here it is downloaded as an app to Launchpad.
It's just an upgrade. With Maverick, it was also downloaded like this to the application folder, and then only the upgrade took place.
Thanks for the answer :) So hopefully nothing will go wrong during the installation.
I just installed Yosemite on the iMac, which also has a BootCamp partition. Well, the problem is, you can boot into Bootcamp and start from Parallels.
I just updated - same case - and no problem.
Thanks for the question. I wanted to ask as well and from the answers it looks like it will be ok.
How is the Recovery HD doing on a clean install? Will it form?
Yes, it will create, but in step #1, when preparing the disk, I would click on the disk and not on the Macintosh HD partition.. this ensures the complete deletion of the contents of the 2 hidden partitions "EFI BOOT" and "RECOVERY", which are re-created during the installation will create
I don't think the installation disc is necessary for a clean install at all, as you write - I just did it by running disk utility (which itself loads from the net in the Yosemite version), formatting it, and then "Reinstalling OS X", which downloads automatically the latest version of the system from the Internet. In 25 minutes complete installation without harakiri with USB…
Personally, I don't trust the Mac OS installation process. It does interesting things when the installation starts from e.g. Mavericks and I install Yosemite on an external HDD, so during installation restarts or after installation I held Alt to select boot from my integrated hdd with Mavericks and what happened? It kept running Yosemite installation for me, I had to start Yosemite from an external drive and switch the boot to Mavericks in the settings, where it did something and it started working. My point is that it does something to the disk from which it is installed (turns it into an installation disk) and I don't like that, in case of any error during the installation, I wouldn't be able to get into Mavericks. When a USB installation is created, it is not only faster but also safer, and since I have Macbooks 2, there was nothing to think about.
so if i do a clean install of yosemite from mavericks, will i be able to restore the original installed programs from the time machine backup? and if so, won't the "mess" from several previous updates be uploaded back there and the clean installation will lose its meaning? thanks :)
Given the way Time Machine works, I'm afraid that the mess will be extended (configuration of programs that you no longer have and the like). The cache and temp will definitely not be transferred to you... Because of this, I preferred to do a clean installation and extract the data from the time machine manually... and start a completely new time machine
Like apple screwed something up again. I did the upgrade and now a window pops up every minute in a row forcing me to log in to iCloud, while I'm logged in, if I close it, it pops up again, not one, but dozens of windows below me, the last time I saw this was when I cycled through Windows 98, that's for real obscenity. Even if I enter a good password, it doesn't help in setting up the iCloud login, I can manage it in any way, but the iCloud Password table still pops up, enter your password for the service and my email.
No one knows what it is. I was in a hurry again, I assumed that the big apple had it easy and not that there would be any shoe.
I would like to ask if I do a clean install of yosemite and I only want to transfer the iphoto and itunes library from time machine, is that possible? I wouldn't like to lose some photos, which I have a lot of on my computer, so I'd rather ask.
hi everyone I'm downloading Yosemite on a MAC via cable, but it's horribly, horribly slow. 700Mega in 2 hours download. I am doing something wrong?
I downloaded yesterday at 23 p.m. and I would say that your problem will be overloaded servers... I'm sure a lot of people will update the OS...
maybe that's really it. In the App store it tells me 5 Incompatible updates. Iphoto Imovie etc… Do you have that there too? I updated everything before downloading Yosemite.
I'm already on Yosemite so it didn't update anything except itunes… are you going to upgrade? because if not, then any updates are messed up.. create an installation medium and boot a clean system
I just clicked upgrade and am waiting to see what happens. Yes, updating iTunes did it. I didn't make the installation media. do i have to I'm not an IT expert.
What you are doing will leave everything you have on your computer, if you are a standard user you will be fine. I had enough configured and tweaked and rather than trying to figure out why it didn't work after the upgrade, I preferred to do a clean install... which is an easy process described in this article, which erases everything on the Mac and installs Mac OS X 10.10 as if you brought Maca from the store :)
How do I restore apps including content such as 1Password during a clean install? Will TimeMachine give me a choice?
Hello, I also downloaded at night, but it's slow, don't be surprised:) everyone is downloading:)
Query? At the end of copying, should a message be displayed in the terminal that it is done? I've been looking at it for a long time, it's still copying and the size of the used space on the flash drive doesn't change.
Thank you
I will answer myself. I tried it a second time with the closed AppStore application where they sent updates. And it already works. He will write it at the end. Done.
I tried to create an installation USB, but it says this: sudo: /Applications/Install OS X Yosemite.app/Contents/Resources/createinstallmedia: command not found.
Can someone smarter advise me? Thank you very much in advance.
so I've been downloading since 06:15 and I've already downloaded 1.25 Gig!!!! :-)
so hopefully it will be done on Sunday.
I downloaded it in 20 minutes. Congested servers probably no longer have…
Hi, I want to ask a few things about reinstalling the system from Maverick to Yosemite. I will be reinstalling the system on the MacBook for the first time, so I want to ask what important steps I should take?
I'll definitely back up my data beforehand - just in case :o)
Then I wonder if the programs that work fine will also work normally on Yosemite (I mean games, for example)
I can't think of anything else that I should do as a precaution, however, if anyone has any other advice, please share it here :)))))
Hello, after a few years I went for a clean install, but I only get:
"installation preparation in progress. The computer will automatically restart" then reports that: "approximately 1s left" and that's where I end... does anyone know what it could be? Thanks
so waiting… it finally started restarting… which is quite enough, after 20 minutes after the message that 1 second is left… Well, nope, mainly that it moved somewhere. Apple is still the best :)
Yes, I wonder if it will be the same case for me too... I'm hanging for 1 hours with 2 second left...
Hi, I haven't had a mac for a long time (09/2013), but when I bought it there was still ML and after upgrading to Mavericks I got iLife (iphoto, imovie, garageband) for free. Since I can't see well, I navigate the system mainly using the keyboard. Well, recently such a thing happened to me - I was uninstalling an application that had a similar name to iphoto and iMovie, and I accidentally deleted it through the Clean My Mac application. Unfortunately, I didn't notice it and only found out after a long time when I wanted to move the photos to iphoto. So I looked in the App Store because I thought - yes, it happened, so I'll download it from the App Store again. To my surprise, there was no install or download but 13,99 euros
I don't have the same experience with osx as I do with Windows, and that's why I want to ask you - the more experienced ones - > Would it be possible to "restore" it using a clean installation of OS X Mavericks downloaded from the App Store? Or will it remember and I have to pay the 13,99? Thank you very much for your answer
Please, how did you do? Did you manage to launch iPhoto? If not, check your account on the Apple store, you should see iLife there in the purchased applications.
Since this is not the case, they give it a free package, yes, but during the first clean installation it is no longer there and can only be purchased through the Mac AppStore. But there is one more solution. It was also described here for apple trees. You need to download the beta version from the net, switch to the English language, the update will run, and after the update it will be permanently added to the purchases.
Or
install normal update from appstore. Reset Mac hold CMD+R
choose disk utility format Macintosh HD exit disk utility and the menu will pop up
install a new OSX and it starts pulling components from the net....In previous versions this method worked...Umna it took about 6 hours on a relatively good line
What with this? After the Yosemite update
Hello, I would like to help with a problem. After installing on Yosemite, sharing doesn't work for me and the notification center is empty except for the following events and doesn't alert me to anything, I can't move it. Could someone give me some advice?
how long did it take to copy the data to the usb? it has been running for an hour and there is only 8 mb on the usn
I had it done on Air and after about 15 minutes I came back to it and everything was done ;-). It takes about 6GB.
Um??? "sudo: /Applications/Install OS X Yosemite.app/Contents/Resources/createinstallmedia: command not found"
sudo /Applications/Install OS X
Yosemite.app/Contents/Resources/createinstallmedia –volume
/Volumes/Untitled –applicationpath /Applications/Install OS X
