unable to update LrC

[Laurence5E4A]

hello, 

I can no longer update LrC since version 11.0, I have a macbook air from 2013 which normally has the minimum configuration required except VRAM which I believe is at 1.5GHz for a minimum at 2GHZ. Do you think it can block updates? I don't have a message saying that I have to upgrade my mac but rather a message that says that updates are not authorized and that I must contact my administrator. I couldn't find any info on this message on the internet... I don't know where to look on my mac to authorize updates.

Thank you for your help

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.

Please provide a screen capture of the 'error' (updates are not authorized).

You are logged in as the admin of this Mac?

That dialog shown doesn't appear to be part of Adobe Creative Cloud. 

Can you open that application and try updating there and tell us what happens:

well, I don't know what I did but lightroom is up to date.

yesterday I updated adobe creative cloud, I closed and reopened ligthroom and still nothing version 11.0. Same tonight. but there after changing the language (which is probably unrelated) to copy the information to you, lightroom reopened in version 11.5.... I don't know how but the problem is solved... thank you for your help.

OK then ignore (or find and delete) whatever is producing this warning which I suspect is from some old, pre-Adobe CC software.

yesterday I updated adobe creative cloud,

Might have been the issue.
