![]() I ran many applications and performed a number of hardware-intensive operations without a single hiccup. I installed the hard drive in the later iMac and booted up not a problem in the world. (If you don’t intend to upgrade your OS version, keep reading anyway this post is still relevant to you.) In the meantime, I could observe the effects of performing such a transplant. I figured that the upgrade process would install whatever drivers were determined appropriate by the installer, resolving any hardware/driver issues. I reasoned that, if any part of the device/driver system wasn’t happy after the transplant, I could simply perform the OS upgrade (from external media, if the system really wouldn’t run properly). My client wanted to upgrade from OSX 10.11 (El Capitan) to OSX 10.13 (High Sierra), as well, and I saw this as an opportunity to experiment. I was asked to transplant a client’s 4TB HDD from a 20” iMac (early 2008) to a 21.5” iMac (mid-2011) and was concerned about compatibility. If it can’t be salvaged, the old OS usually works passably to get your data backed up so you can restart with a fresh installation on the new system. If you can, I would see if you can get the system working well enough to do a Time Machine backup and have that as a failsafe just in case (or to have a backup to start fresh if the old install is due for a refresh anyway). This is a well known limitation on how far you can take it. It doesn’t always work (Ex: Core Duo original to a Core 2 Duo/Core i series with a dual video subsystem may not boot), but it usually does in most situations well enough to get your data and wipe the system. The reason this generally ends up working is Max OS X is more receptive to total system changes compared to Windows. It typically works if the system is similar, but if it’s too radically different you may need to take a backup and start over. Yes, but there are no guarantees the system will boot with your old configuration or operating system. If Apple won't get a more consumer-friendly policy, then they should restock inadequate computers people buy because they can't test first. Your best option may be to purchase the computer you think will work, transfer your data from your old Mac/Time Machine using Migration Assistant, test your apps, and take your new computer back immediately if it doesn't satisfy your need. ![]() If you're dealing directly with the Apple Store, you have to "buy before you try". This is irritating since they stopped installing pro apps like Photoshop on the demo systems. This means that you can't walk in with an external drive and boot the computer into your own setup for testing purposes, or with an older Mac in target drive mode. They're spooked by malware, even though they're likely to be booting into guest accounts which could be wiped at shutdown. Apple Store note: For the last few years (since 2015 at least, and maybe for a long time before), Apple Store staff won't let you to connect an external drive to a demo computer.
