The reason listed for System Update is typically generic and vague, and I notice no changes or improvement to added functionality or performance.
Yesterday I powered up my Maxi Sys Elite and saw 5 updates available including System Update. After I did the System Update and restarted Maxi Sys App , it opened up displaying the apps on the page in a very gradual slow manner. I waited awhile and the other 4 available updates never popped back up and displayed again. Weird stuff.
I have a 64gb unit with 27.52gb of available space still,so I don't think a lack of space caused the unit to almost fail to boot up. IMO all these System updates every other week are just gonna scramble the Sh@t out of things. LOL
