Samsung 840, TRIM disabled for two months:

Samsung 840, TRIM enabled again, SSD freshly trimmed using fsck command:

Note that this is an older Samsung 840 (not "EVO"), so your experiences might be different. But I have experienced a similar speed degradation (noticeable in real life) with my previous Samsung SSD (SATA-1, don't remember the model). TRIM fixed it.

That is a drastic difference. How full is your drive?

I'm still kind of afraid to reenable it on my work laptop. It's been all around flakey recently, I'll tough it out until it's time for a replacement.
 
Photos app on iMac Mid 2007 doesn't export videos.

Does anyone have the issue of not being able to export videos from the OS X Photo's app on 10.10.3 to say for example dragging and dropping on to their desktop?

Both using the Export function and dragging and dropping work for me.
 
Haha no.

Did you also experience the bug in Mail.app where parts of its table view freeze and show only a few mails which do not react to clicks anymore. I have to kill the process via "pkill Mail" and restart to fix it.

Hopefully they fixed that one in 8.2 (2096)

I have an 840 Pro in a DIY Fusion drive. Same thing -- without trim, this thing slows down to like 15MB/s writes. I have to enable trim to keep it writing faster than a spinning drive.
 
Maybe when this version of Yosemite is released (beyond the betas) I will be able to update from Mavericks.

Thank you, early adopters.

––––––––––
Now, someone please tell me how this is better than Mavericks.
 
I can see what's going to happen here. Yosemite will just about become ok and then Apple will release another "fantastic" OS which will be full of bugs. A year later, that will be stable then they release...I'm sure you get the idea.

We (ok, I) don't need a new OS every year. I used Windows XP for 6 years. It was pretty good in 2001 and even better by 2007. Most of industry (not office staff...industrial use) still uses it because it's solid as a rock. That's what I want..a Mac OS that's as solid as a rock!

Are you saying that using Windows XP is a more stable experience than using OS X 10.10.2 Yosemite? Not in the universe I live in at least. :)

Yosemite works well for me overall. Stable and fast in general. Nothing major to complain about. At least not worse than Mavericks for me. :)
 
Unless the SSD is Apple OEM, make sure to turn off TRIM before doing any system updates, SMC or PRAM resets. If you forget, you will have the same problem. After the update is completed, you can turn TRIM back on.

This did not present a problem for me. I had patched using the last 0.9.9g beta of Chameleon SSD Optimizer, installed over the top of it, which wrote a new kext, and then after rebooting I ran the optimizer again and it was fine. I was running the previous public beta and just upgraded in place.

I was referring to the the most common TRIM app used called Cindori
 
Yup. Completely unable to use my internet connection at all when Photos is uploading. They need to implement some intelligent throttling, because I am forever pausing it for a day and forgetting to put it back on when I go to bed.

This has always happened to me. I was assuming it was my 512MB upload speed. Looking at iCloud upload speeds - isn't actually that fast.
 
But they all do the same thing, patching the kext in place: https://gist.github.com/return1/4058659

Just because it worked fine for you with your program, that doesn't mean that everyone should follow suit.

The creator of the app I cited (which is one that is the most used) highly recommends that people turn off TRIM before updating etc. That is what I was addressing. I am not here to debate over different TRIM apps.

Actually, XP SP3 with all the subsequent many years of patches put in, was/is quite stable. There's a reason companies didn't want to budge from it. I had heavily used machines that I didn't have to reboot for more than a year, if ever. Though I wouldn't call it secure at all! Craphole security! That's the main reason to upgrade.

Windows 8.1 is not even now at the level of stability of XP SP3 though its approaching it.
 
is there anything new in Photos with this beta?

One thing that hasn't changed is, you still can't upload photos to sites like Facebook, while using Safari, like you could with iPhotos. Clicking on the Photos library doesn't allow you to view and choose individual pictures.

However, the Flickr Uploader now lets you add the Photos library to the queue of pictures it will automatically backup for you, which is nice. Things are advancing.

I thought this too, but I just noticed (and this might not be new to this beta) that if you select "Photos" under the Media heading in the sidebar you can browse your Photos app library. Selecting "Pictures" however doesn't work.
