A hefty (almost) 3Gb download. That’s quite a bit for a point release.
Apple’s macOS updates have come to a point where they are on par with Microsoft Windows 95. Several restarts. Unreliable times (from 43 minutes immediately to 9 and then it took around 30 minutes). Different screen resolutions. Screens going black and returning to a status bar. I have really no clue what’s going on here.
I must say that the latest Windows 10 updates have been smoother.
Catalina took 8 months to get to 10.15.5, probably will take one more to get to x.6. (High Sierra was 10 months to get to that point.) But it came out with two supplemental updates in the first two weeks of release, then x.1 a week after that. Four releases in October - an unprecedentedly difficult release.
Mojave took 20 months to get to 10.14.6. I typically update when a Mac OS gets to x.4 but I’m glad I’ve continued to wait this time. Mojave has been solid and I like still having my 32-bit apps and legacy music plugins.
Unfortunately I bought a 16" MBP to replace my 9 year old 15" MBP. That forced the upgrade to Catalina. All of my 32-bit app issues have been resolved but one, there doesn’t seem to be a replacement for MPEG Streamclip. (I can always run the Windows version in a VM.)
At least you have options. I still have some plugins that won’t make the 64-bit transition, along with some 32-bit apps and utilities with no equivalent. (For example this ‘retired’ editor of text and picture clippings.)
What if I say, your Email ID is all I need to takeover your account on your favorite website or an app. Sounds scary, right? This is what a bug in Sign in with Apple allowed me to do.
In the month of April, I found a zero-day in Sign in with Apple that affected third-party applications which were using it and didn’t implement their own additional security measures. This bug could have resulted in a full account takeover of user accounts on that third party application irrespective of a victim having a valid Apple ID or not.
For this vulnerability, I was paid $100,000 by Apple under their Apple Security Bounty program.
