Hi Pat,

 

Something you could try is running the inbuilt Mac hardware testing diagnostics 
- depending on what the problem is it may or may not work/help - but worth a 
try.

 

I don't know what the age or OSX version is for your MacPro but:

 
For Macs released before June 2013 run Apple Hardware test 
https://support.apple.com/en-au/HT201257
For Macs released after June 2013 run Apple Diagnostics 
https://support.apple.com/en-au/HT202731
See also https://support.apple.com/en-au/guide/mac-help/mh35727/mac
 

Be aware that these tests can take some time to complete - so be patient.

 

As I say, this may or may not identify a problem - but it is probably a good 
place to start.

 

 

HTH

 

 

Cheers

 

 

Neil

    Hello, WAMUG,

    

    I am currently living in Brisbane, and my Mac Pro computer seems to be 
dying. I am hoping someone will recognise the symptoms and possibly have some 
suggestions that might help.

    

    When I press the start button, the chime happens as it should, and it seems 
to start. But all too soon, like, 5 minutes, it quits.  Then it chimes again 
and quits again, repeats again and again until I turn it off.

    

    I thought possibly it was heating up too much, but the temp inside the room 
 is cool.   Or something might have been wrongly connected.

                Any ideas??

    

    Hoping all of you are still well,

    

                Pat Scott
