Hello ~

I am trying to update my MacBook Pro software which I haven't done in a few years. I currently have OS X El Capitan 10.11.6. I tried to install a software update to get the current operating system which I believe is Catalina 10.15.6. I went to my "About this Mac" and clicked the software update option and updated "all" and restarted my computer after the downloads finished. It is still showing El Capitan.

Also, I had iTunes on earlier today and went to sync my iPhone but my phone was not showing up in iTunes. After I did the software update listed above (which showed iTunes and Safari) and restarted my computer I tried to open iTunes I got an error message that says the application can not be opened.

So - basically I have 3 problems which I can't figure it out. 1) Software won't update 2) I need to back up my iPhone 3) What happened to iTunes

Help me please and thank you, they are the magic words.

Tracy
 
I just went to the app store and got a message that says "We could not complete your purchase. This version of macOS 10.15.6 cannot be installed on this computer". ????
 
What year is your MBP?

I looked up the serial number on Apple's site and it says 15-inch, Late 2008. Dang! I can't believe I have had it that long. Still going strong. I love Macs.

OP:

You need to tell us WHICH MBP you have, WHAT YEAR it was made.

I suggest you try Mojave instead of Catalina.
BE AWARE that Catalina will "break" older software you may have, that is "32-bit".
That stuff just won't run any more.

Try this link for Mojave:

Hi - I looked up the serial number W88511TY1G0 and it is a late 2008 model. I can't believe I've had it that long. Go Mac!!! I'll check out Mojave. TY
 
OP:
If you have El Cap installed now, just "run with it".

If you want to keep using the 2008 MBP a little longer, and if you still have a platter-based hard drive inside, you might look into replacing it with a cheap SSD. 250 or 500gb, I wouldn't spend any more than that. When the time comes for a replacement Mac, you can take the SSD OUT of the old MBP, put it into an external enclosure, and re-purpose it.

I'm not sure about the drive replacement procedure on a 2008.
Go to ifixit.com to see what's involved.
If you do the job, BE SURE TO USE THE RIGHT TOOLS.
