If you play Sims 4 in Windows through Steam and have purchased Sims 4 DLC (Expansion, Game and Stuff Packs and Kits) through Steam, this content will not be available to you if you switch to Mac. There is no Steam version of the game available for Mac users so you will be switching to using Origin (or EA App at some point when it is released for Mac). DLC is not transferable between Steam and Origin for Mac. Furthermore, you will need to unlink your Steam account from your EA account to even get the base game to run on a Mac as it interferes with your game entitlement in Origin.

The quickest and easiest solution to this problem is to create a new EA account, log into Origin using that account and download the base game for free. Use this account to purchase or redeem DLC to add to your game.

The other alternative is to unlink your EA and Steam accounts and then download the base game for free and purchase/redeem DLC to add to your game in Origin.

To be clear, you do not need to purchase DLC through Origin. If you prefer to use a 3rd party site (not advisable unless it’s one of EA’s approved retailers, there are some dodgy sites out there), you can simply redeem the product code in Origin.

Quick guide on choosing a decent external drive to install The Sims 4 on and using for the Sims 4 or Electronic Arts folder if creating a symlink. The drive and connection you use is REALLY important. It needs to be as fast as possible otherwise you will experience endless loading and horrible in-game lagging, if you get that far. I am an external drive junkie, I have loads of them, and have experimented with a ton of different drives over the years. The current one I have settled on, and is perfect with loading speeds and connection, is the Samsung T7. I love how small and light it is too.

What NOT to use:

HDD (Hard Disk Drive). These are the old style drives which manufacturers have gradually moved away from. HDDs have a spinning disk which the computer reads data from and writes data to (for example, the operating system reads the game data to load it and writes data when applying a patch. Similarly, the game reads the save file to load the save and then writes to the save file when you save). Think of it like a record deck only much smaller and only reading, not writing. HDDs are still available to buy and are typically very cheap now. They come in two speeds – 5400rpm and 7200rpm. Neither of which are fast by today’s standards. They have a higher rate of failure and can be easily damaged if dropped as they have physical moving parts. If the product description does not specifically state SSD storage then the drive will most likely be a HDD. Do not use one of these.
A USB-A connection
An adapter cable from USB-C or Thunderbolt (Mac) to USB-A (external drive) to enable a connection. Adapter cables are great and fix the physical problem of connecting an incompatible drive to a computer but are only as fast as the original connection.

What to use:

SSD (Solid-State Drive) or a Flash storage thumb drive with a direct USB-C/Thunderbolt connection and at least USB 3.2 speed with read/write speeds of around 1,050/1,000 MB/s.
External drive “Transfer” speed and “read/write” speed should not be confused when it comes to running a game through an external drive. The read/write speed is the drive spec. you should be looking at.

Why do I want to use an external drive?

Pro – to install the game externally so it doesn’t fill up internal disk space on your Mac.
Pro – if you have two or more Macs running the game through the same Origin/EA ID you can install the game on one external drive and switch it between Macs rather then install the game on each Mac.
Pro – by creating a symlink you can store your Sims 4 or Electronic Arts folder on the external drive, bypassing the default location in your Documents folder. Especially useful if you have a lot of CC/Mods taking up masses of precious memory and a ton of save files.
Con – good quality fast SSDs are still a little pricey.
Con – cannot play the game unless you have the external drive with you.

Best practice and how to use:

Always wait for your Mac to fully mount the drive before opening Origin. You should see it either on the desktop or in the Finder sidebar depending on your Mac setup.
Once mounted, open the drive and navigate to the deepest level folder to make sure the operating system has fully loaded the contents. This is especially important on slow drives.
- If using for your game installation, open the Sims 4 Packs folder and then several pack folders and subfolders.
- If using for your Sims 4/Electronic Arts folder, open the saves folder and then the Mods folder (if you use Mods) and a subfolder.
Never open Origin without having the drive plugged in. It will default to the internal drive location and will require you to set up the external drive location again in Origin > Installs & Saves > Game library location.
If the symlink is setup for the Sims 4/Electronic Arts folder, never launch the game without the external drive plugged in. You will get the game is already running error message.
Once you’ve found a drive you think will work, always do a little research into the read/write speeds of the drive. If the specs aren’t immediately apparent in the product description you should google the drive and “read/write speeds” to get a proper idea. If the drive is unbelievably cheap the chances are that it’s going to be pretty slow.
