If you skipped the macOS update prompt for Ulaa, as shown in the screenshot below, you may occasionally be unable to update Ulaa from the About page. In such cases, follow these steps to resolve the issue:
1. Open Terminal : Launch the Terminal application on your Mac.
2. Run the Command : Copy and paste the following command into the Terminal, then press Enter:
defaults delete com.primeum.Browser SUSkippedVersion
Note : In a recent release, we have removed the macOS update prompt. Updating should now occur seamlessly in future versions. You may encounter this prompt only if you lack write access to the Mac’s application directory.
