Hello @justoriana,
My name is Henry and I am happy to assist with your inquiry, and appreciate you contacting LastPass Support!
The LastPass mac app is now downloaded from the Apple app store, the current version is 4.130.0. Please follow the steps from this article to uninstall the old version of the app and download the new one from the app store.
Please let me know if this worked or if further assistance is required.
Thank you,
Henry | Customer Care
