Enable Trim on Leopard?

I decided to install Leopard on a small partition of my MacBook hard drive for PowerPC apps instead of hooking up my G5 all the time and everything is working just fine but I cannot find a way to enable TRIM, everywhere online is people asking how to on a PowerPC Mac, but mine is Intel so it should be there right?

Also, mods, yes this is for an Intel Mac but if I ask over there they might not have the slightest clue about anything 10.5.8 related.
 
Since TRIM support was added in Snow Leopard 10.6.6, you're out of luck.
Why are you still using Leopard on an Intel Mac? Snow Leopard is great, supports even the first Intel Macs and still supports PowerPC apps if that's what you're after.

Best of my knowledge there is no way to add / enable Trim on Leopard. @val1984's suggestion to use Snow Leopard would also be my recommendation for PPC compatibility on an Intel machine.

I duel boot it with 10.11 so I can use Final Cut 4.5. And I hear Leopard emulates PowerPC apps faster than Snow Leopard, thats why I went with Leopard. Snow Leopard emulates them as if it were an 800MHz G4 (so I've read) but Leopard emulates it based on a faster PowerPC CPU (so I've read)

There's no significant difference in emulation speed between the two. Emulation speed is directly related to the actual speed of the CPU. The improved compatibility with everything else will make it much easier to use 10.6.8 than any version of Leopard.

I honestly was going to go 10.6 but my legit Snow Leopard 10.6.3 DVD went bad so I used my Leopard USB I used on my iBook awhile ago. Well, off to ThePirateBay I guess.
 
For starters - There's common reports of malware included with system installer torrents. OS X is not alone in that.

Is your DVD physically broken, or badly scratched? If not, you can usually make a copy of that DVD (to a dual-layer DVD), and that copy will work fine.
Even better, you can also make a partition on a hard drive, then copy the DVD, using Disk Utility/Restore function, to that partition. It would be bootable, and is a more reliable way to install OS X. An 8GB USB flash drive is ideal for that use.

Correct me if i'm wrong, but didn't snow leopard ditch Carbon?
So there may be a reason (good reason? debatable, but still) to run 10.5.


edit:
but yeah, emulation speed, no difference. Snow leopard is better than leopard in all respects IMHO - unless you need Carbon and it isn't included (i'm not 100% sure, but i think i recall seeing a message about missing carbon support back in 09 on my Mini when i upgraded it to 10.6 with some ancient game).

Yeah, my disk is badly scratched. I didn't think OS X could be hit with Malware like that though. I only figured that was a risk with Windows. Dumb to think, but yeah I'll just try and make a copy of my snow leopard dvd and it might work. It can still be used but takes around 15+ hours to install OS X and even bootcamp drivers. Flopping it over to a new DVD would probably help then.

Carbon is still supported in 10.11 and will be in 10.12 too and I don't think it's going away anytime soon.
The only thing regarding Carbon is that it can't be used to write 64-bit apps but 32-bit apps run without problems on 10.11 (and I don't think that's going away anytime soon too).

You could try to make a USB key installer then.
 
Snow Leopard was the last OS X system that could run PowerPC-coded apps (Remember Rosetta?)
That emulation layer of support for PPC apps was dropped in Lion, so if your fav app does not have universal binary code included, then it won't run after upgrading to Lion or later.

Carbon support is not part of the issue about support for PPC-only apps.

Aware that SL can run PPC, it's why i keep it around and WISH (and asked Apple) they would allow you to run the desktop version in a VM legally.

However i'm sure there was something that wouldn't run in 10.6 that i could run previously in 10.5.

It's been that long now though. Either way, if its just PPC you want, run 10.6. And look for new software because you're insecure...

It seems incorporating this function into OS X is difficult.
How about a utility that sends trimming command to the SSD manually?
You just have to run it from time to time. Yeah, there is no PPC OS X version exist.
But at least it looks like an easier route.

I'll be glad to review your code when its ready to release.

If you are willing to pay shipping, I've got a spare 10.6 disk. PM me.

After Lion came out and they slashed the price of Server (now just an "app" rather than a proper server OS costing hundreds of £/$) you could call Apple and order Snow Leopard Server for a very low price (it was never listed on the online store) being sure to make clear you wanted Server and not the client version, I got the full retail 10.6 Server box set for £14 plus shipping from them - I'm guessing they have run out by now though.

Lever said anything about Lion? I duel boot with El Capitan and Leopard and talked on upgrading to Snow Leopard. Lion isn't a part of this yo

You guys and torrents jeezus. Download Transmission (which is ad free), then find the 10.6.3 SL Retail DVD. There is no malware included with it and is a straight DMG that you can use to burn to a DVD.

Yeah, I figured it'd be just fine. I'm not dumb enough to think Malware is entirely impossible to be on a Mac but I really never thought an OS X installer dmg from Kickasstorrents or Thepiratebay would be totally infested.

If there's no malware in the DMG file, what about Transmission itself? ;)

This was patched pretty quick, but it's still enough to make me stay away from Transmission. My older ad-free version of uTorrent still works just fine.

I always only use uTorrent. Had bad first impressions with Transmission back in like 2010 just simply not working. So I went to uTorrent and never used anything else.
