MacGPS Pro is Going Totally Mobile

With sad hearts, we must inform you that Apple recently announced that they are phasing out 32-bit Mac application support. Some applications will be affected in the the fall of 2018, and the rest will no longer be supported at all by Apple under the future 2019 macOS upgrade. The map files in MacGPS Pro use the 32-bit-only PICT format and hence will no longer be usable with future Apple macOS system software updates. Also Garmin has reduced the compatibility of many of their newer receivers with 3rd party software such as MacGPS Pro. The vast majority of our MacGPS Pro customers have switched to using our apps mostly on iOS devices rather than on their less-portable Mac computers. Therefore, we have made the decision to stop selling new copies of our Mac products on January 31, 2018.

Please know that we are not abandoning you as our customer! Your MacGPS Pro program and all of its maps will continue to work on your current Mac as long as you either don't upgrade the operating system beyond macOS 10.13 High Sierra, or you download the free Parallels Desktop Lite application and install macOS High Sierra or earlier on its virtual machine. Support for the MacGPS Pro program and MacTopos maps will still be available to you via phone call, email, or logging in to your account on the MacGPS web site.

This decision will allow us to provide more frequent updates with exciting new features to our mobile apps for the iPhone and iPad: iHikeGPS and iSailGPS. Many of you already have made the transition from MacGPS Pro and Mac laptops to using our iHikeGPS or iSailGPS with your iPhone or iPad. This transition has convinced us that iOS apps are the way to go for navigation in the field, so we will invest our full programming force towards the future.

We want to thank you for being our customer by providing one last opportunity to complete your collection of MacTopos maps at sale prices while they are still available for purchase. On-Sale Maps and Charts

As a further thank you for those using an older version of MacGPS Pro, we are offering a free upgrade to MacGPS Pro 10.4.6 with every MacTopos order placed in January 2018. You will receive an email within 5 business days after your map order is placed with a link to your free MacGPS Pro upgrade. If you don't get the emailed link, please check your junk email box. If you still don't see it, please let us know.

Again, thank you for using MacGPS Pro, and we look forward to your continued enjoyment of our iHikeGPS and iSailGPS apps. Enjoy the great outdoors!
