Can't navigate macOS Tahoe 26.0.1 on MacBook Pro
I brought my 2025 MacBook Pro to the Apple Store for some problems; they decided the computer needed to be wiped and reset. Luckily most things were backed up on iCloud however now, with this new system, EVERYTHING is screwy.
The only way I can access Safari is via the small button in my dock, then an entire Safari option appears & I have to select Email before I can access my Email.
There's an obnoxious calendar, clock, and photo that appear on my desktop and I can't get rid of them.
I can't Airdrop photos where I can find them.
There are no options for icons to ID the various items in the Menu Bar.
And so, SO, many other problems. I want my old OS back - the one I understood, the one that wasn't not totally different.
Can anyone guide me on how to understand this totally new system? Or, otherwise, how to return to my old OS?
Thanks in advance,
