Version Affected:  All

Version Fixed:  Varies by application

Issue: In February 2018, Apple announced that they would begin phasing out support for 32-bit applications, starting with the release of macOS 10.13.4. Apple is expected to end all support for these applications with the release of macOS 10.15 (Catalina) in Fall 2019. This means that once Mac users upgrade to macOS 10.15 (Catalina) in autumn 2019, the three remaining 32-bit Lasergene applications will fail to launch: SeqMan Pro, GeneQuest, and classic GenVision.

Users of macOS 10.13.4 and later who are running Lasergene 16.0 will receive a warning message from Apple when first opening a 32-bit Lasergene application. Users running Lasergene 15.3 will NOT see this warning.  The text of the message will resemble the following: “<Application name> may affect the performance of your Mac. The developer of this app needs to update it to improve its compatibility. [OK].” After the [OK] button is pressed, the warning will disappear and is not expected to reappear in subsequent launches of the same application.

Resolution: Between the 15.1 and 16.0 releases, most DNASTAR applications were updated to become fully 64-bit compliant. We are working to update our remaining 32-bit applications–SeqMan Pro, GeneQuest, and classic GenVision–to 64-bit compliance. Our plan is to have all applications compliant with the release of Lasergene 17 in early 2020.

We recommend that Mac users who wish to use SeqMan Pro, GeneQuest and/or classic GenVision postpone updating to macOS 10.15 (Catalina) until after the release of Lasergene 17.
