Numbers 3.6.2 won't open 1 spreadsheet, says need to update. But can't update to newer iOS on 13" 2012 MacBook pro
I'm stuck have mid 2012 13" MacBook Pro maxed out on Catalina. Numbers says I need latest iOS to update it.
But I had been able to work with it & existing spreadsheets & new ones. But a few days ago it won't let me open 1 I need. But I can open a newer one I have created. I had recently updated the spreadsheet that it will not let me open now. Nothing has changed that I know of.
I realize its time to upgrade to a new computer but I'm confused since just in last few days it has stopped letting me open a spreadsheet I use w list of meds & supplements.
So I'm planning to upgrade soon after I do a little more shopping. But any help in being able to access existing spreadsheets in mean time? I also need to finish my income taxes. Couldn't use TurboTax this year. Had to use H&R Block which i don't like.
So any suggestions so I can continue to use existing spreadsheets for the time being? Or why it lets me open 1 but not the other? I usually like to update & take this one it won't let me open when going to visit medical providers.
