For Mac users looking to use GHL products, there has been some concern that the programming software is PC based. Most concerns have been alleviated with the cloud, www.MyGHL.com, but sometimes you still need to use GHL Control Center on the PC. There's 3 options for Mac users. 1. Run an emulation software like Parallels. 2. Format your mac with Bootcamp and install Windows. 3. Purchase a PC and Windows. I prefer to do most programming with the Control Center software and I've run all three options. The emulation software is "ok". But I found it to run slow and be buggy. It got me by, but it was a bit of a pain at times. Its not cheap either. You have to purchase the emulation software and Windows. This was my least favorite option. Bootcamp on my Mac was great. It ran smooth, fast, no problems. The downside was needing to reboot when you want to run windows. Then reboot again to get back to Mac Land. Bootcamp is free/included with your mac, but you will have to purchase a copy of Windows. You also lose a sizable chunk of your hard drive space to the new partition. My favorite option is #3. It sounds expensive at first but it's actually not. We're so used to Apple prices, we forget how cheap PC's are. I picked up a NextBook Flexx 10 which is a tablet that runs full Windows 10. It was around $140 at the time and came with Windows. So for $140 I got a fully functioning PC and it can run next to my mac. You can shop ebay for used ones. The exact same one is up there now for $60. Your Mac remains completely untainted. This is by far the most hassle free option and less expensive than Option #1. So if you want to run the best, most reliable controller, doser, etc on the market but are afraid because it's not specifically Mac-based, no worries. You have a few options to choose from and it's not scary at all. Pretty simple, actually. Are you a Mac and GHL user? Please add your experience!
