My Mac Studio was hanging up real bad after the update. Called Apple Support and after an evaluation I was advised to reload macOS 15. This was a real learning experience for a relatively new Mac user. I now know how to go into safe mode on the Mac and what I can do from there. The setup is so much better than how it works on a PC. I noticed the value of the 4TB SSD that I formatted to APFS it was displayed as an internal drive.
