lightroom classic CC freezes on startup on Mac Mojave during 2 minutes

I do not know if this is possible, but on your reply, that you marked as correct, does an option to unmark as correct show up? Members often sort on unanswered.

see (ref 1), note that updating LrC is included. Also see (ref 2) for some history on LrC updates/upgrades.

3.I don't like the prescription way Adobe uses to distribute their programs. I bought Lightroom as a stand alone version and I do not want to pay every month for very minor upgrades I don't need or use.  I don't like the way the moneymachine Adobe works.  I will update and pay for it when I want to, not  the way they oblige me to make monthly donations !
There are other competitors who make excellent software that you buy and OWN !!.

Those two bits of info/reply do not match up. From the above, I see:

v7.2 is subscription. So you must be paying for an Adobe Plan, most likely the Photography Plan.

1. Did your problem get resolved?
2. Any reason your MACOS is still Mojave (10.14.6),  Is system requirements for newer MACOS beyond your computers age?
3. Same question for LrC version, yikes v7.2? , current is v10.4

(ref 1)  macOS Catalina is compatible with these computers

(ref 2)  macOS Big Sur - Technical Specifications

(ref 3)  Lightroom Classic system requirements (October 2020 release (version 10.0) and later)

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.
