You can mix them fine but you will need the disc of the latest expansion pack you have installed (in order of release) to play.
If you install the latest one as download, you won't need a disc to play.
You can download every game you own on disc through Origin though. They should be in myGames to download.
You can use your DVD codes. If you registered the games should already be in myGames.
I don't know too much about the mac issues but there are many since Sims 3 is not native to macs. Best to ask in the mac forum on the official site. They can give you all the details.

Do I have to pay for the download online or do I just use the codes that I have in my digital copies???
Also, does sims 3 work well on mac? There's very mixed reviews!
Hello
I have pasted below some instructions on using Origin on Mac, in case you decide to go with that option. The game does work on Macs, but you need to do a bit of extra work to get it running, because of the way it was made to work on the Mac operating system. I have therefore also pasted some tips for Mac simmers.
In general, your best chance is to have plenty of RAM and to purge it manually while playing, a decent graphics card and save often.

Using Origin on Mac
Download and install the Origin client for Mac and make sure it is up-to-date. If you already have Origin on your Mac but are having problems with downloading or installing games, delete the client and download a new copy (this sometimes fixes issues with downloading). The latest version can be downloaded from here: http://www.dm.origin.com/mac/download
Additional advice on how to download games (thank you Tremayne for this tip):
When downloading from Origin, do NOT use the first install icon. Move your cursor over the game cover and click on the information (letter i) and then click on the install button from there. For some reason, downloads from Origin frequently become corrupted. Using the i reduces the chance of your download being corrupted. If you have already been unfortunate and have a corrupted download, then it is important to remove all traces of this before trying again, by doing a thorough, clean uninstallation first.
Are you running anti-virus software or any clean-up applications? If so, disable these, as they might be deleting files that Origin needs. A fast, stable internet connection will also help you.
Mac simming
Unfortunately a lot of TS3 players encounter problems when playing the game on their Mac. These can include crashing and freezing. A lot of these issues can be avoided or at least improved by the following measures.
Firstly, manually reset your RAM while playing. See BluebellFlora's guide on how to do this: http://bluebellflora.com/the-sims-3-on-a-mac/resetting-ram-during-gameplay/
I restart my computer before I play TS3. The memory used as seen in Activity Monitor is at about 3GB after the restart. If I open the Launcher it goes up to around 11 GB (that's all I've done - just opened the Launcher!). At this point I reset the RAM. Then I hit play and get through the opening sequence. I then press cmd-return to put the game in windowed mode from time to time while playing (and always before saving or using CAS). That way I can keep an eye on the memory and reset RAM if necessary. Being in windowed mode also allows you to close the game using force quit if it freezes up - it's better to crash the game than your whole computer.
Second tip is to save frequently. I save at least once per sim day. Use the option to Save or Save As, rather than the combined Save and Quit.
Make sure you are patched up to date. The 1.63 patch included fixes for Mac simmers that did actually improve the stability of the game on our operating systems, so it is well worth updating.
