Numbers software
Is there a version of Numbers which will run on my iMac OS X El Capitan, Version 10.11.6?
(1.6GHz Intel Core i5)
If so a link to download would be great.
If not, suggestions for a simple free spreadsheet software app.
The matching version of Numbers is Numbers 3.6.2. Apple does not maintain full installers for previous version of Numbers at the App Store, but if you have previously purchased or got Numbers from the App store, you may be able to obtain this version.
Log on to the App store using the same Apple ID as the earlier version was attached to.
Click on Purchases.
If Numbers is on the purchase list, click that entry.
I've not done this, and may be missing some of the details. You will likely get more complete instructions by reposting this as a Pages question in the Pages community. The process will be the same, but Viking OS X is likely able to provide a more precise response.
