[MAC] Present editor lags on Safari

Just started using the free Prezi to see if it would be a good fit to use on my presentation classes.
Using a MacBook Pro with OS 12.0.1.
Safari 15.1

When starting a new presentation on the site everything moves with a severe time lag. For example it takes several seconds for a letter to be deleted after pressing the delete key. Then am unable to add new text. When moving an object it takes even longer to see the results of dragging it to the new location.

Any way to fix this?

Thanks for reading. Stay safe and enjoy!

Edit: added browser information.

Hello @Con_Buc, thanks for reporting this.

Could you please check if it has the same lag on a different browser, for example, Google Chrome?

Could you also tell me which exact MacBook Pro do you have?


I am using a

MacBook Pro (13-inch, 2019, Two Thunderbolt 3 ports)

Processor: 1.4 GHz Quad-Core Intel Core i5

Memory: 8 GB 2133 MHz LPDDR3

Graphics Intel Iris Plus Graphics 645 1536 MB

It works better on Chrome, but there is still some lag. Not nearly as much compared to Safari but some.

Hope this helps.


Hello @Con_Buc, the system specifications should be fine for Prezi Present.
Based on the information provided, I see no reason for the performance drop.

Could you please ensure you have your device’s latest Mac OS version and see if that helps with the performance issue?
