ACASIS TB501 Pro Gen 5 SSD Firmware Problems Thunderbolt 5 MacBook Mac mini M1 M2 M3 M4 M5 UPDATE

TO BE CLEAR: When I talk about the date of the 9th, I'm talking about the 9th of September 2025, which is a couple of days before recording this video.

Just some more information about the firmware issues with the PCIe Gen 5 NVMe M.2 SSD compatible version of the Acasis TB501 Pro 80Gbps Thunderbolt 5 NVMe SSD enclosure for Apple Silicon Mac computers such as the M1, M2, M3, M4, M5 versions of the MacBook Pro, MacBook Air, Mac Studio, Mac Studio Ultra, Mac mini, Mac mini Pro, iMac.

Sorry if the title and description for this video seem like clickbait word salad. I am just trying to get this video noticed as much as possible as the things that I am talking about are very important and will be affecting a lot more people than those who watch my videos. It's those people that need to know that they may have issues with their Acasis TB501 Pro that they don't know about.
