Hello @eastman228,
My name is Henry and I am happy to assist with your inquiry, and appreciate you contacting LastPass Support!
I am sorry about the issues you are having with the Mac App. In case you have not downloaded the app directly from the Apple App Store, please uninstall the app and reinstall it. Please also be sure, that your device meets the minimum system requirements for LastPass.
Please let me know if this worked or if further assistance is required.
Thank you,
Henry | Customer Care
Nothing works I uninstalled and reinstalled several times, but no luck Even if I can get the app to install it will not launch from the vault or fill in when I launch from bookmarks. I may have to use Apple password manager on my MAC Last pass works on my Windows desktop, my ipad and my iphone. This problem just started today. I appreciate your help. Uninstall and reinstall usually works. This time I have no idea what is causing the problem. Thanks
After uninstalling and reinstalling Last Pass a couple times, I finally got an app that asked me if I would let them access a site and I selected all sites and now it is working. The last MAC update may have caused the problem. Thanks for the help
