The history appears as it used to, but I have been unable to access any older versions through it. I've attempted from VMs of older OS versions to recreate the App Store as it used to be in El Capitan & High Sierra, to see if I could still access the old 'purchase history'. We may need direct links for these, which I don't have at present. Some further testing is required - contributions welcome - to see if other OS versions are similarly removed. Testing the El Capitan installer which has a published URL it will appear in the App Store, but if requested to download no longer says 'not valid for this Mac' it now says 'The requested version of macOS is not available'. Sierra, High Sierra & Mojave are available via direct links - see below. It would appear that in the new Mojave App Store, older purchased OS Installers no longer appear at all, so the 'simple method' of grabbing it from your purchase history is no longer valid. Some users seem to have managed to skip El Capitan, but High Sierra still seems necessary. This will prepare your machine for the long jump. If you are trying to jump a long way - say from 10.8 to 10.14 or later, received wisdom is to first upgrade to El Capitan 10.11, then High Sierra 10.13. One thing that still applies throughout: you need a Mac to get macOS easily & legitimately. Now that Apple has startup keys to help recovery select multiple versions and official knowledge articles, it might be simpler to first check Apple's own page on How to download macOS (which didn't exist when this Q&A started out), then come back here if you still have issues. I was able to get a 30-day trial of pixelmator online, which I'm using for now.Every year / release this answer on installing previous versions of macOS will need updating. PS, I'm having the same issue trying to download 1Password and Pixelmator. It seems ridiculous to get a whole new computer for just a single app, and one that I had before my hard drive failed! Is there any place I can download an older version of iPhoto? I don't know what to do, but I need iPhoto.

And my computer doesn't support any OS past 10.7.

I went to the App Store to re-download it, but it said you need OS X 10.10 to download iPhoto.

A lot of my stuff is saved in Google Drive, so for the most part I was ok, but one really annoying thing is that iPhoto was no longer on my computer, which I use quite a bit. I installed a new drive into it, and got it going again, though I had to start from scratch. I was using it happily until last week, when my hard drive suddenly failed. About a year ago I acquired a white Macbook (model A1181, 2007 version) running OS X Lion.
