There may be a few members who use Jumpcut as their Clipboard Manager. It is basic, free, text only; but has been going for the last 8 years or thereabouts.

With Catalina on the horizon, it has been updated as a 64Bit app under the auspices of GitHub.

Why I'm posting this is - if you have the old version, it will offer the update each time you open Jumpcut or reboot your Mac.

But this does NOT work. You will get an error report.

For those interested, the update can be found here: Jumpcut

I stress that I have absolutely no associations with this product or company other than as a long time user.
