Being a registered developer I thought I'd download the first beta (12.0) today and install it on my 2020 MacBook Pro - which is my 'junk' Mac, in that I use it to play with beta software and such like. As with Big Sur it's excellent off the bat. Very, very fast indeed and lots of nice features, one being that Safari now takes its toolbar colour from the website background...



Pretty. Tab handling is very nice on Safari too.

Not a single problem or issue found so far on my boot volume, testing it now.



**EDIT**

One issue found. Safari scrolling is hit and miss. No doubt that'll get sorted, bug report sent.
