Did Mavericks drop support for express card SSDs?

So what happened with Apple

What is the hidden agenda on this issue as one might think this bug has been introduced on perpose, when it's solved so easely by users but totally neglected by Apple.

if it's not solved with Mac OS X 10.9.2 may we conclude it's a set-up?

Hennie, there's no hidden agenda at all. Apple, like every other computer company, wants you to buy the latest and greatest product. They have very little motivation to sink money into fixing a problem with a component that, let's all be honest, is very near deprecation. In fact, Apple is probably more motivated not to fix the problem because it will force people to upgrade their systems sooner than they would have, generating more revenue for the company. It doesn't make the issue any less frustrating for those of us dealing with it, but it is, unfortunately, the reality of computer life cycles.

Hi all, I have that ExpressCard problem but where is my IOPCIFamily.kext file? 😟 I don't have one and I also can't install one with the Kext Wizard, it says „differet version /uuid already loaded“.

Oh ok I just clicked the wrong button in the Kext Wizard. Everything is working now.

So additional information: Even if there is no IOPCIFamily.kext file in the folder, you can install one with the Kext Wizard and the ExpressCard slot will work again.

Apple. This is too easy. Why not implement this in a OS X update? Unbelievable.

Yeah...it had to be too good to be true. Things worked well for me. However, now finder hangs. As soon as I turn off my drive tower, things are normal. I'm on a mid-year 2010 box with OS X 10.9.1 I have the expresscard 3|4 standard. I eight drives in my tower. Things where great but now not so much. This process has damaged one of my drives. For the kind of cash I laid out, I'm besides myself. My total investment is near ten grand. What kind of company does this? Unbelievable!!!

I finally got around to replacing the kext file. I really didn't want to do it but I couldn't wait any longer for an official fix. So far it seems to be working for my Wintec 128GB SSD.

I have a Caldigit USB 3.0 express card that I still need to try....

Thanks for the unofficial fix!

siaccarino, Have you got around to see which agents or daemons were causing your issue?

Read my post earlier in this thread. My Caldigit express card work fine for me but I did make bootable drives before I tried, just in case. ;-)

I just tried it without drivers and it did not work for me.

I installed the driver and then it worked just fine.

Folks, if you're still following this thread, the 10.9.2 update restores ExpressCard Slot functionality on 2010 17" MacBook Pros.

Whew, about time!! 126 days.

Do we need to put back the original kext or will the mountain lion one be over written by this update?

IT not the only thing fixed. The fixed a Security issue that came up yesterday (That's right you heard right, discovered yesterday). Now would Microsoft get something that quick.

I'm planning to buy an expresscard/34 card for USB3, for my 2010 macbook 17".

Does anyone know whether 10.9.2 will allow all chipsets for USB3 to function, or only some?

I just upgraded to 10.9.2, and I did not have to back out the hack patch. My Wintex 128GB SSD still works fine.

I left the computer running but when I returned, it had rebooted after a panic, but the Wintec SSD had not remounted. Shutting down and using the power switch to restart rebooted everything successfully, and the Wintec SSD remounted. All is using my mid 2010 MacBook Pro 17"

The panic was caused by not releasing a vnode (vnode_rele() or whatever it's called for the reference counting of vnodes for you other kernel hackers out there,) The BSD process was mds_store. Although I don't have any more concrete information, this looks very similar to what I saw before when I first installed the Wintec SSD and it ran out of space. I fixed this before using TRIM enabler, so that I wasn't just relying on garbage collection to recycle deleted space on the drive. Sure enough, TRIM enabled had been disabled, probably by the installation of 10.9.2 (it was not disabled when I upgraded to 10.9.1). I updated TRIM enabler, rebooted, and everything seems fine now.

Your mileage may vary, but it really does look as though you should enabled TRIM on all SSD drives in 10.9.x (I also have a Crucial m4 550GB as the main drive.)
