Unable to open photo software now

I want to thank all who have responded to request for help. I had to free up a little space on my MacBook Air, and then I deleted all versions of ON1 Photo Raw again, backed up everything, and was able to reinstall MacOS. Then, I reinstalled On1 Photo Raw 26, and IT WORKED!!! I am so grateful. Because I only noticed issues with On1 Photo, I thought that was where the problem started. But THANK YOU!!!!

Do have ON1 PhotoRAW perpetual license or the ON1 PhotoRAW Max which is the subscription version?

Something else to try, create a second admin user on your Mac, log into it, and try to open the ON1 app. If it opens, it will probably ask for license credentials. The fact that if it opens at all with a different user can be a clue something is corrupt in your user account. If it does open, enter your licensing stuff and see if it fully opens. If this works quit and try to open again. If it continues to open then most certainly something is corrupt in your original user account. I have come across this a few times over the years.

If the second user attempts also fail to open the app, then there is some fundamental issue with the combination of the app, the OS, and any other items you have installed or previously uninstalled (perhaps incompletely).

Reinstalling the OS but NOT first erasing the Mac is the simplest way to reinstall and it is fairly benign (the OS is on a separate read-only sealed volume from the volume with all your data, emails, photos, etc.) and it might restore a system component that is missing. Also, sometimes files in the user area that point to certain system files may be missing, and the OS reinstall MAY restore those as well.

If you have any app cleaners, optimizers, third party security or network security or anti-virus software, those can certainly interfere. Sometimes the app cleaner software (an example is CleanMyMac) may remove certain files that it somehow thinks are not needed and that can lead to symptoms like yours. Yours may have a different root cause but it's something to be aware of.

which specific MacBook Air model do you have and what macOS version is it running (open Apple menu and About this Mac...)?

FWIW, I have been using ON1 PhotoRAW for a few years now and all the macOS versions in that period up to and including the current macOS Golden Gate and the latest version of ON1 PhotoRAW and have not had such an issue. The Macs that I have used with ON1 are an M1 MacBook Air which had macOS Big Sur which I bought back in 2020 and currently on my M4 MacBook Air.

So, info on your Mac and the OS it is running may help. Also, have you tried re-installing macOS?

It may or may not be meaningful, but how much free disk space do you have?

I have done all those things several times, without any different outcome. Thank you.
