Today, I upgraded my MacBook to Tahoe, the latest Apple operating system. To say that it has been a disaster would be an understatement. It has left my computer in a near-unusable state. I spent the bulk of the day trying to debug the various issues. I have made some progress, but many apps are still working oddly or locking up intermittently, and opening certain files can take tens of minutes.

To downgrade to the previous operating system, I will need to completely erase my hard disk, which will require a full backup of my photos, videos, and data. Given how slow my computer is working, this could take days, if not weeks. I ordered a 4TB drive, which is expected to arrive on Saturday for this purpose.
