Problems with PowerPoint fo Mac

[NWAGrandpa]

I'm running MS PowerPoint 2011 on my early 2011 MacBook Pro with MacOS High Sierra, 10.13.3.
During certain operations such as selecting Slideshow, the system often hesitates, then closes PowerPoint and generates an error message. Happens frequently. Also happens sometimes when changing text format or copy and paste operations.

I use Office 2016 for my Mac, although not PowerPoint. Do you have the latest version of Office 2011 for the Mac? From a google search, this seems to be the most recent one:

However, it looks like Microsft released a Security Update for Office 2011 back in July:

Also, as of October 11, 2017, Microsoft will no longer support Office 2011. But according to a statement contained within this link:

https://www.macrumors.com/2017/10/11/microsoft-office-for-mac-2011-support-ends/

Office 2011 works with High Sierra.

Sorry I could not be more help.

Since all the i-works programs, Keynote, Numbers and Pages are free on all recent Macs, and get free updates for OSX, and that files produced within them are easily 'translated' to & from Windows apps such as Microsoft Office - including PowerPoint - as well as to Adobe (.pdf), I find it odd that people continue to pay Microsoft's annual fees.

Some of them then complain about lack of compatibility or are mystified when something ceases to work.

I moved from Windows some years ago and also use 'Open Office', another free download exactly compatible with MS Office.

I have always accepted all OS and iOS updates as they arrive, and apart from my first MacBook (white 2009) which now struggles a bit, none of our MacBooks, my i-Mac, nor our several i-Pads & i-Phone have had problems. I diligently use ONYX and Norton Security. Never have I had the multiple difficulties I suffered with Windows in various incarnations over many years. I am so glad I made the change to where all updates are included in the original retail purchase price.

I also use Onyx (have been using for many, many years), along with Tech Tool Pro and SuperDuper!, once a week (typically on Saturdays) to perform disk cleanup/maintenance/repairs, and backups for both of my Macs. That, and diligently doing disk cleanup on my own every day, keeps my Macs "lean, mean, and clean". And I rarely, if evrr, have issues.
