Mac Os High Sierra Unsupported

  



The soon to be unsupported macOS 10.13 High Sierra was released three years ago, and Apple releases a new major update for its desktop OS every year in the fall season. Insert your desired USB drive, open Disk Utility, and format it as OS X Extended (Journaled). 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.

macOS 10.13 ('High Sierra') became available from the Mac App Store in September 2017. Since the release of macOS 10.14 in September 2018 its support status is unclear.

The information below is for historical reference only.

There are some important actions to take before you install it:

  1. Ensure that all the software you are using is compatible with it. See below for a list of known issues.
  2. Verify your hard-disk or SSD before doing the install.
  3. Make sure you have a recent backup, allowing you to recover your data in case of problems.
  4. Note that the upgrade will most likely convert the filesystem on your Mac, carefully read https://support.apple.com/en-us/HT208018 and re-check your backups!

Known Issues

This is a summary of issues known so far. Please note that this list is by no means complete. Please contact the Service Desk if you encounter a problem with an application or a service.

Adobe Illustrator CC

Adobe is reporting about several known issues with macOS 10.13, see https://helpx.adobe.com/illustrator/kb/illustrator-and-mac-os-high-sier…

Auristor Client

Auristor client versions lower than 0.160 are not compatible with macOS 10.13 and must be uninstalled or upgraded before attempting to upgrade to macOS 10.13. Failing to do so will result in endless kernel panic - reboot - kernel panic cycles. We do not recommend to use the Auristor client. Also see the entry for OpenAFS below.

Mac Os High Sierra Supported Devices

AutoCAD

AutoCAD 2017 can not be installed on a Mac running 10.13, but it might work if it is installed before the upgrade to 10.13

GPGTools

According to https://gpgtools.org (link is external) there is a release of the GPG Suite for macOS 10.13 (GPG Suite 2018.1).

hpglview

hpglview does not work with Xquartz versions above 2.7.9. Xquartz version 2.7.10 or newer is required for compatibility with X libraries on lxplus et al. For the recommened version of Xquartz see below.

MacPorts

Mac Os High Sierra Problems

MacPorts users should read https://trac.macports.org/wiki/HighSierraProblems, before upgrading to macOS 10.13.

MATLAB

MATLAB versions below R2017b are not compatible with macOS 10.13.

Messenger

Mac

Messenger has dropped the support for gTalk.

Microsoft Office

Microsoft Office 2016 requires at least version 15.35 for macOS 10.13.
Support for Office 2011 has stopped in October 10th, 2017.

OpenAFS

We are not aware of a working OpenAFS client for macOS 10.13. The previous versions of openAFS client do not work under 10.13. You must de-install OpenAFS before upgrading to macOS 10.13. Failing to do so will result in endless kernel panic - reboot - kernel panic cycles. Please note that AFS is being phased out at CERN. In the transition period a scp from or to lxplus might be sufficient for infrequent access to AFS files.

Parallels

Parallels has a list of known issues and potential fixes or workarounds on http://kb.parallels.com/123840

ssh

Some GSSAPI options have been dropped already in macOS 10.12. Among others the GSSAPITrustDNS is not supported any more. You might have to remove the unsupported options from the system and / or users ssh config files.

In the past we recommended to keep an old version of the ssh binary that still supported GSSAPITrustDNS. This is not needed anymore since lxplus and other major services have now been configured to use service keys. See http://information-technology.web.cern.ch/services/fe/mac-support/howto/configure-ssh-password-less-login-lxplus-or-other-linux-boxen.

System Center Endpoint Protection

Older versions of SCEP do not work on 10.13. Make sure to update your SCEP version 4.5.32. before updating to macOS 10.13.

XQuartz

It is recommended to use XQuartz 2.7.11 or later (https://www.xquartz.org/ (link is external)).

XQuartz installs into /opt/X11, and creates symlinks in /usr. If you have previously installed any version of X11 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.

Apple previously released security updates to defend against Spectre—a series of speculative execution vulnerabilities affecting devices with ARM-based and Intel CPUs. Intel has disclosed additional Spectre vulnerabilities, called Microarchitectural Data Sampling (MDS), that apply to desktop and notebook computers with Intel CPUs, including all modern Mac computers.

macOS Mojave 10.14.5 includes security updates for Safari, and the option to enable full mitigation, as described below.

Security Update 2019-003 High Sierra and Security Update 2019-003 Sierra include the option to enable full mitigation.

About security fixes in macOS Mojave

macOS Mojave 10.14.5 fixes this issue for Safari with no measurable performance impact.1 This update prevents exploitation of these vulnerabilities via JavaScript or as a result of navigating to a malicious website in Safari.

Customers can also protect their Mac by updating security settings in macOS to download apps only from the App Store. This setting helps prevent the installation of apps that could potentially exploit these vulnerabilities. All apps from the App Store are signed by Apple to ensure that they haven’t been tampered with or altered. Learn how to view and change app security settings on your Mac.

Although there are no known exploits affecting customers at the time of this writing, customers with computers at heightened risk or who run untrusted software on their Mac can optionally enable full mitigation to prevent harmful apps from exploiting these vulnerabilities. Full mitigation requires using the Terminal app to enable an additional CPU instruction and disable hyper-threading processing technology. This capability is available for macOS Mojave, High Sierra, and Sierra in the latest security updates and may reduce performance by up to 40 percent2, with the most impact on intensive computing tasks that are highly multithreaded. Learn how to enable full mitigation.

Unsupported Mac models

These Mac models may receive security updates in macOS Mojave, High Sierra or Sierra, but are unable to support the fixes and mitigations due to a lack of microcode updates from Intel.
