MacOS Catalina 'Verifying Files'

The worst of this is that Apple's release notes say NOTHING of the problem; why it might have occurred; or what had to be done to fix it. I have not yet installed the update, but will do so as soon as I can. This time I'll cross fingers and toes.

I'm not sure the Catalina update completely fixed the problem. Late 2013 iMac went going through verification process for some apps after update 10.15.2 and csrutil enable in recovery mode. Not all apps, however! Can close and reopen apps w/o repeat verification, so that fixed...Also, I don't know what reboot will do (yet!). As others observed, things seem much quicker on Catalina on this older MAC.

I have the same situation on my late 2012 Mac mini. Only one of my apps (parallels toolbox) goes through a verify when booting. I have rebooted several times and the verification is consistent.

I contacted Parallels support and sent them the diagnostics data as well as a video of the verify.

I can relate. I reverted to Mojave and at the moment I’m still able to develop with latest XCode, but you’re right, usually Apple eventually forces us to update. I know it’s only a matter of time...

That was not the only problem before the update. The verification process often produced no results and had to be repeated multiple times to get the program to launch.

Perhaps the worst part of the experience is that Apple has never acknowledged how f’ed up this release was, or that we were seemingly used as lab rats. I still have not given up the idea of dropping Apple, after decades of loyalty. This time, the company **** on its most loyal fans and is incapable of apologizing.

2012 MBA Air here. Still running strong, but also seeing this after update to Catalina. Seems to be anything in my login items - Dropbox, Google Sync & Share, and Garmin Express. I've verified all are up-to-date.

I am also having huge delays problems with verifying files after upgrading to Catalina. iMac late 2013 27inch, 3.4 ghz, quad i5, 16gb, Catalina 10.15.2 installed, hard drives and memory check ok. Something is seriously wrong with the OS upgrade to Catalina..not resolved

Nope, it's not the disk hardware - I have a iMac pro with a 1TB SSD - what should be instantaneous opens now take several seconds, even something as simple as an image to open in Preview. It appears that the operating system no longer pops up a dialog saying "verifying", but it is in fact verifying. Unbelievable. As a pro user I need this fixed. 10/16 needs to be a maintenance release that resolves these issues. It feels like I'm back in 2006 running Windows Vista.

I've got the same problem with not just Microsoft apps but Apple and Adobe apps too. So slow waiting for these.

Im having the same problem after updating to Catalina on a MacBook Pro Retina early 2015 model. All apps have to verify now when being opened..

Same issue here iMac late 2013 very frustrating!

I am having the same issue. My Mac is running super slow. I have tried a new user and safe mode. No difference.

Any help would be great.

Same here. iMac 27 late 2015. Every time I open a program I have to wait a minute or two for it to be 'verified'. This is infuriating. How do I turn off this feature?

I have the same problem on my Mac late 2013 version.

Adobe, Microsoft and a couple of other programs.

There has to be fix, patch to Catalina soon I suppose.
