Help! iPhoto Library Upgrader tool endless loop
I am at the end of my rope with this issue. I have tried everything I know. I have read all the old forums from 2013 and 2014 on this issue and nothing works.
I had a 2007 macbook that I used till 2014. I uploaded all my photos into iPhoto during those years. I backed up my whole macbook onto a 500 GB external hard drive before I got rid of the old Macbook in 2014. At that time I bought a new Macbook air in 2014 and have not been using iPhoto since that time (now using more iCloud and Google photos).
I simply want to go and access those old pictures I saved into iPhoto on my hard drive.
When I click to open it I get this message:
So I clicked "Learn More" and downloaded the iPhoto upgrader tool. It goes into the utilities folder. So I go there and double click it. It asks me for a library to upgrader. I choose the one from my hard drive and I get this message:
So I click "Repair" and I get this message:
So I think everything will now work. But when I click "Launch iPhoto" it gives me the same darn original message again!!!
It is an endless loop. I cannot get it to work. Apple used to be so easy to use and this issue has frustrated me to no end.
For those wondering, I am using iPhoto version 9.6.1 on a Macbook Air running Sierra 10.12.6. I am not sure what the old version of iPhoto I was using in 2013/2014 on my old Macbook but I always kept the software up to date on my computer.
MacBook Air (13-inch, Early 2014), macOS Sierra (10.12.6)
