MacOS Sequoia 15 Vulnerability

There is a critical flaw in MacOS’s latest update, MacOS Sequoia (15.0), which is causing Macs to become inoperable.

If you have not yet updated your Mac device, TSI strongly advises against upgrading to MacOS Sequoia (15.0 ) due to known issues that may render the Mac unable to access the internet, or, in the worst case, un-bootable.

If you have already upgraded your Mac and everything is functioning normally, you can assume that your system is operating as expected, and no further action is needed.

However, if you are experiencing issues following the upgrade, please contact the TSI Help Desk immediately. In such cases, your device may need to be wiped and reloaded with an earlier version of the operating system.

As a general best practice, TSI recommends waiting a few weeks after the launch of a new operating system before upgrading. This allows time for the identification and resolution of potential issues and is a useful tip for upgrading any operating systems, including Windows, Linux, and MacOS.

Thank you for your attention to this manner and we look forward to following up with any additional updates as they arise.
