In the Overview tab, look at the Mac model year below the OS version number. If the year is the same or above the previous compatibility list, then you should be able to install macOS Catalina formally. If not, read on. Make your old Mac support macOS Catalina. Older Mac owners don't have to worry. It's not the end of the world. Related tutorial: How to use Disk Utility to format drives on your Mac. 3) Download a copy of macOS Sierra 10.12. To download this via the Mac App Store you will need access to a supported machine. However, a direct download or a download inside a macOS VM can circumvent this requirement. All Late 2009 and later MacBook and iMac models are supported in macOS Sierra, as are all 2010 and newer MacBook Air, MacBook Pro, Mac mini, and Mac Pro computers. Hacking macOS Sierra for Unsupported Macs. Hardware requirements for macOS Sierre include a CPU with SSE4.1, so it cannot be run on any Mac with a CPU prior to the Penryn Core 2 Duo. OS X El Capitan on Unsupported Macs. MacOS Extractor, OS X Patcher, and MacPostFactor are apps that guide you through patching and installing OS X El Capitan (10.11), Yosemite (10.10), Mavericks(10.9), or Mountain Lion (10.8) on your older Mac.
Alternatively, If all you want is a a compilation environment for Objective-C, C, and Swift v4.n, the Command Line Tools (macOS 10.13) for Xcode will provide that at 7GB less storage. You would then need a competent programmer's editor, and you can still build hand-coded cocoa applications. This is my preference.
macOS 10.12 ('Sierra') became available from the Mac App Store on September 20th, 2016. It has been superceded by macOS 10.13 ('High Sierra'), released in September 2017. Since the release of macOS 10.15 on October 7th, 2109 it is unsupported.

There are three important actions to take before you install it:
- Ensure that all the software you are using is compatible with it. See below for a list of known issues.
- Verify your hard-disk or SSD before doing the install.
- Make sure you have a recent backup, allowing you to recover your data in case of problems.
Known Issues

Authentication
Using Network Groups from Active Directory (egroups in CERN speak) does not work out of the box. To be able to use Network Groups from Active Directory you have to increase the timeout for replies from the server, otherwise the request will fail and the user can not log in. To increase the timeout you should run
sudo /usr/libexec/PlistBuddy -c 'Set :Modules:SystemCache:Membership Query Timeout in Seconds 20' /Library/Preferences/OpenDirectory/opendirectoryd.plist
Please note that this is only needed if you want to enable network groups from AD - if you enable individual AD accounts this is not needed.
Calendar.app
The problem syncing imported .ics calendar entries with the Exchange Server has been fixed :)

GPGTools
According to https://gpgtools.org there is a beta3 release of the GPG Suite for macOS 10.12.
MacPorts Alfred powerpack 3 5 1.
Previous versions of MacPorts are not compatible with macOS 10.12, according to https://trac.macports.org/wiki/SierraProblems MacPorts needs to be reinstalled.
Mail.app
- Adding multiple exchange accounts requires prepending 'CERN' to the email-address. Without the prepended 'CERN' you will get the mesage 'The account exists already'.
- We get occassional reports about Mail.app stopping to fetch new messages. We don't have the impression that the frequency of this is higher than with previous versions of Mail.app. But at least re-creating a deleted account appears to be much faster than with previous versions of Mail.app.
MATLAB
Usage on mac. macOS Sierra requires MATLAB version 2106b released on October 6th 2016. All previous versions (including previous versions of 2016b) had serious issues with many non-United States regions and locales. 3d free software cad.
OpenAFS
Vlc media player mac os x download. The previous openAFS client does not work under 10.12 (you get kernel panic a each shutdown/restart), it is recommened to uninstall it before upgrading to 10.12.
A working client is announced on https://wiki.openafs.org/admin/BinaryThirdParty/, please read the description carefully before installing the client.
ServiceNow
Only relevant for supporters: When you go to ServiceNow with Safari 10, the old interface (UI11) is rendered. The only work-around is to use another browser. For more information check https://cern.service-now.com/service-portal/article.do?n=KB0004247 .
ssh
Some GSSAPI options have been dropped. Among others the GSSAPITrustDNS is not supported any more. As a result password-less logins to services that use DNS round-robin for load balancing (lxplus, svn, aiadm,.) will not work any more.
As a work-around you can save the ssh binary from 10.11 and use that with 10.12.
XQuartz
Macos Big Sur On Unsupported Mac
It is recommended to use XQuartz 2.7.10 or later (https://www.xquartz.org/).
Macos Sierra Unsupported Mac
XQuartz installs into /opt/X11 now, and creates symlinks in /usr. If you have one of the previous versions of XQuartz that did install in /usr, the symlink /usr/X11 -> /opt/X11 cannot be installed, and some X programs will not start. In that case you have to remove the directory /usr/X11 and manually create the symlink.
I also have a YouTube video going over the whole process.
Requirements:
- Early-2008 or newer Mac Pro, iMac, or MacBook Pro(MacPro 3,1 and 4,1, iMac 8,1 and 9,1, MacBook Pro 4,1, 5,1 5,2, 5,3,5,4, and 5,5)

-- The 2007 iMac 7,1 is compatible if the CPU is upgraded to a Penryn-based Core 2 Duo, such as a T9300.
- 2006-2008 MacBooks (MacBook 1,1, 2,1 3,1 and 4,1)
- 2008 MacBook Air (MacBookAir 1,1)
-- Note: Make sure SIP is disabled on the system you intend to installHigh Sierra on. If it's not or you're unsure, just boot into your Recoverypartition of your currently installed copy of OS X, open Terminal, andrun 'csrutil disable'.
Things you'll need:
- A copy of the macOS High Sierra InstallerApp. This can be obtained from the Mac App Store using a machinethatsupports High Sierra, or by using the built-in downloading feature of the tool. In the Menu Bar, simply select 'Tools > Download macOS High Sierra.'
- A USB drive that's at least 8 GB in size
- A copy of the tool - Download here (Current version: 2.7.0, SHA1: 73f180d30200ef5f6d900440fe57b9c7d22bd6bf)
-- View changelog and download older versions here
Known issues:
- Trackpad (MacBook5,2 affected only). The trackpad in the MacBook5,2isn't fully supported in High Sierra. While it works and is fully usable,High Sierra detects it as just a standard mouse, preventing you fromchanging some trackpad-oriented settings.
How to use:
1. Insert your desired USB drive, open Disk Utility, and format it as OS X Extended (Journaled).
2. Open the 'macOS High Sierra Patcher' tool, and browse for your copy of the macOS High Sierra Installer App.
*Ensure that the tool successfully verifies the app.
3. Next, select your USB drive in the Target Volume list, and click 'Start Operation.'
4. When the operation completes, boot your target unsupported Mac offthe USB drive you just created by holding down the Option key while turning on the machine, and selecting the drive.
Note: Only perform steps 5 and 6 if you intend to do a clean install.Otherwise, you can simply skip these steps and install to your volumecontaing a previous version of OS X, and it'll do an in-place upgrade.
5. When the installer boots, open Disk Utility from the Utilities menu, or by double-clicking it in the Utilities window on the bottom left corner of the screen.
6. Select the disk or partition you want to install on, and erase it,ensuring to use either Mac OS Extended (Journaled), or APFS as the filesystem type.If formatting an entire drive, ensure GUID is selected.
-- Please note that if you use APFS, you will not have a bootable Recovery partition.
-- It is recommended that you only use APFS if the target drive is an SSD.
-- If you decide to use APFS, a custom booting method will be installed by the post-install tool, as the firmware of these unsupported machines does not natively support booting from APFS volumes. It is not quite as clean as native booting, but will not cause any issues while running High Sierra. A demo of the modified booting process can be viewed here.
7. Install macOS normally onto the desired volume.
8. When the install completes, reboot back onto the installer drive.This time, open the 'macOS Post Install' application.
9. In the application, select the Mac model you are using. The optimalpatches will be selected for you based on the model you select. You canalso select other patches of your choosing.
-- The 'i' button next to each patch will show more details about the respective patch.
10. Select the volume you have just installed macOS High Sierra on, andclick 'Patch.' When it finishes patching, click 'Reboot'. It may sitthere for a few moments rebuilding caches before rebooting.
-- If for somereason the system fails to work correctly after rebooting, boot backinto your installer drive, run the post install patch again, and select'Force Cache Rebuild' before rebooting. This isn't necessary under mostcircumstances.
11. When it reboots, it should now boot into a fully working copy ofmacOS High Sierra.
Additional Info:
- If selected in the macOS Post Install tool, your High Sierra install will have a program named 'Patch Updater' located in your /Applications/Utilities folder. This program will alert you when new updates to patches are available for your machine, and will prompt you to install them. If you do not have Patch Updater installed, but would like it, you can download and run the script found here to do so.
Updates
System updates, such as 10.13.1, should install normally if 'Software Update Patch' was selected in the macOS Post Install tool, or installed using the Patch Updater program. If for some reason updates aren't showing up, or you did not apply the patch, you can install it manually using the script found here.
-- If the machine does not start up properly after applying a system update, you will need to boot off your patched installer volume, and re-run the post-install patch on your High Sierra volume. Ensure you select 'Force Cache Rebuild' before rebooting.
FAQ:
Q: The tool created the USB drive successfully, but when booting, the progress bar hangs a bit more than half way.
A: Check your copy of the Install macOS High Sierra App. If you're using thelatest version of the tool, you must be using the latest version of theInstall macOS High Sierra App. Version 1.1 ofthe patch tool and older support older versions of the installer app.
Q: The patch tool gives me errors, such as 'Error copying files.'.
A: Check to make sure your USB drive is writeable. Try re-formatting it, or just try a different USB drive.
Q: The patch tool gives me a 'Mounting Failed' error
A: Check to make sure your Install macOS High Sierra App is the correct one.It should be around 5GB in size. If you used the 'Skip AppVerification' option, you have most likely selected an invalid app thatdoesn't contain the necessary files.
Q: I cannot open my copy of Install macOS High Sierra with the patch tool.
A: If you downloaded the copy linked above, it is distributed inside aDMG file. You must open this file (mount it) to access the InstallmacOS High Sierra App you need to select.
Q: I don't see my hard drive partition in the installer screen or in the post-install tool.
A: Make sure FileVault is disabled, or use the instructions found here to unlock it manually using Terminal.
Q: I get a 'NO' symbol when starting up after successfully installing High Sierra.
A: Make sure you have run the post-install patch on the correct volume, as detailed above in steps 8-10.
Q: I get a 'NO' symbol when starting up from the patched USB drive
A: Check the supported/not supported list at the top of this page. Ensure your machine is in the supported list.
Q: My iSight camera doesn't work after installing High Sierra
A: Make sure you properly remove (using the program's uninstaller, not by simply dragging the application to the Trash) all virtual machine software installed on your machine, such as VirtualBox, VMWare, etc.
Q: I get 'NSURL' errors when trying to update my machine or use the App Store
A: This is usually the result of having an invalid CatalogURL set. To revert to stock, simply run 'sudo softwareupdate --clear-catalog' in Terminal, and then run the software update patch script located above.
Q: Safari, App Store, and/or Mail stopped working after installing a system update
A: Download and run the Onyx application, select 'Maintenence' at the top, then click the Run button.
Q: I get a 'No packages were eligible for install' error when attepting to install High Sierra
A: This is due to your system's date and time being set incorrectly. To fix it, you can either boot into your current OS X install and set the date, or you can use Terminal after booting from your patched USB installer drive to set the date. Instructions to set the date using Terminal can be found here.
