Ondrej Holzman Already on September keynote we are they found out, that the new OS X El Capitan operating system for Macs will be released on September 30. Back then, however, Apple only subtly hid this information in its presentation. Today he confirmed tomorrow's release of El Capitan.
OS X El Capitan, like several of its predecessors, will be completely free to download from the Mac App Store. For many users, however, this will not be such a big news, because a public test program ran throughout the summer, in which ordinary users could also try OS X El Capitan and its new functions.
"The feedback from our OS X beta program has been incredibly positive, and we think customers will love their Macs even more with El Capitan." he said to tomorrow's official launch of the new system Craig Federighi, senior vice president of software engineering.
Apple's latest computer operating system, which will bring improvements to core applications but also improved performance and stability of the entire system, will run on all Macs introduced since 2009 and even some from 2007 and 2008.
The following Macs are compatible with OS X El Capitan (not all features work on all, such as Handoff or Continuity):
- iMac (Mid 2007 and newer)
- MacBook (aluminum late 2008 or early 2009 and later)
- MacBook Pro (Mid/Late 2007 and newer)
- MacBook Air (late 2008 and later)
- Mac mini (early 2009 and later)
- Mac Pro (early 2008 and later)
How to create an OS X El Capitan installation disc
Once you download OS X El Capitan from the Mac App Store tomorrow, there's a perfect opportunity to create an installation disc with the new system before the installation itself. This is useful if you want to install OS X El Capitan on other computers or at some point in the future, because the installation disc eliminates the need to download a several gigabyte installation file from the Mac App Store. As soon as you install the new system, the installation file disappears.
The procedure is exactly the same for OS X El Capitan like last year with OS X Yosemite, just slightly modify the command in Terminal. You will then only need at least an 8GB USB stick.
- 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 El Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install OS X El Capitan.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.
How is El Capitan doing with the op. memory? Does it perform the same as Yosemite or better/worse? Is it safe to upgrade the system with applications left? Thanks!
El Capitan will run with 2GB of RAM, but at least 4GB is recommended. Upgrading with the current system including applications is not a problem.
I currently have Yosemite on an MBA 13″ with 4GB and I haven't experienced any problems, so El Capitan will probably be fine too. I'm just a bit worried that for example MacPorts (and other programs in the cli) won't cause me some problem. Is there a possibility to go back to the state before the upgrade after the upgrade (ie also to Yosemite)?
Give yourself a disk image via Disk Utility on an external disk. :) Then it should be possible to revert it via CMD+R, at least I used this procedure when I migrated from an older SSD to a newer one.
Just make a TimeMachine backup, boot into recovery and return to Yosemite (the backup is marked with version 10.10, etc.)
Captain seems better to me than Yosemite. With the captain, with certain applications and programs, the fan, which under Yosemite was running at maximum speed, became quiet again.
The only fault with the captain is that it doesn't support totalfinder, etc. That's the only thing that bothers me, and hopefully it will change over time.
So it should be compatible from Monday, I just don't know what "Disable SIP" is
Capitan has a new built-in protection that "guards" the access rights/authorization of the application.
Oh, great, thanks a lot. I read something about it but I don't know it was called SIP so I was wondering if they did something else.
Anyway, from what I'm reading about it, I'd be happy if I could go into "advanced mode" where I'd enable system modification only for TotalFinder, I probably won't turn it off globally :-( And I'll switch to PathFinder
Um, try visiting Apple support or some foreign forum and ask about this. So I would be quite interested if it is possible to grant some exceptions instead of a global on/off.
From what I've seen so far, it seems not. Because people climb into recovery mode to turn it off or change kernel parameters at boot:
E.g.
sudo nvram boot-args=”rootless=0″; sudo reboot
Or cmd+R at startup and then csrutil disable terminal
I don't have El Capitan to look at the manual pages (man csrutil), but I'm guessing it won't be that tight...
So I found a development PDF directly from Apple, I don't know if you can read it, but if there are developers who make, for example, kexts (modules for the core of the system), then Apple recommends turning off SIP completely and there are also instructions.
The csrutil utility itself only has:
enable - turn on
disable – turn off
status – displays the status
So I calculate, in 10.12 it could be…

What to switch to XtraFinder https://www.trankynam.com/xtrafinder/ ? I have no problem with it on El Capitan.
I'm curious to see how much metal will show up, for example, when working with FCPX :)
Hello, do I have to have os x yosemite installed in order to upgrade to os x el capitan, or can I upgrade directly from os x Mavericks? Thank you
greetings to you all,... do you happen to know when it will be available for download? porpipad when I download develop. version, won't it be "truncated" somehow? That some programs won't run under it?
Tonight at 8
Techradar: "Named after a granite rock formation in Yosemite Valley, it's expected to emerge at around 18:00 GMT time this evening."
but according to that, it worked out to be 19:00
So far, nothing - it's 19:30pm and El Capitan is nowhere to be found. Just update Safari
Here is the official link https://itunes.apple.com/us/app/os-x-el-capitan/id1018109117?mt=12
I have 100GB of internet via fiber optics and in one hour of downloading I have the entire 1GB of 6 :-)
Hmm, I have 25mbps and already downloaded :-)
I have 15MB from O2 and in 20 minutes I have almost 2GB at home. That I would take the mercy of O2? :D
Don't you have a new file for Czech spelling on El Capitan?
The one for Mac OS X 10.6.7 is not compatible and the installation failed. :-/
A version for 10.11 El Capitan is already available link: http://www.macweb.cz/ceska-slovenska-kontrola-pravopisu-pro-mac-os-10-11-el-capitan/
