Issues clearing storage on Macbook in order to update to new macOS
Hi there, I am trying to update the macOS of my Macbook to Monterey, but am having issues, I think partly because it is still on a really old version (Yosemite 10.10.5). This Macbook has had little use up until recently which is why it hasn't been updated for so long.
It apparently will need 44GB free to install the update, but only has 31GB free after clearing out everything possible. There are no photos stored on the Macbook that I can see, but it says that 39.27GB is taken up by photos?
I have gone into Photos and cleared the trash folder in there (although there weren't many photos in the first place) as well as clearing the normal Trash in the dock.
I have tried syncing my iPhone to it to see if it has any old stored back ups, but I'm unable to do this because the OS version is too old to allow them to sync.
Any ideas on what else I can do to find these supposed photos or access any previous back ups?
Thanks in advance.
