mavericks.pngApple today seeded build 13D45a of OS X 10.9.3 to developers, just under a week after releasing the seventh OS X beta, build 13D43, and over a month after the first 10.9.3 beta.

The beta is available through the Software Update mechanism in the Mac App Store as well as through the Mac Dev Center.

Apple continues to ask developers to focus on Graphics Drivers, Audio, Mail, Contacts and Calendar sync over USB in iTunes, and Safari. As was discovered with the first beta, 10.9.3 adds new support for 4K displays, offering "Retina" resolutions that improve readability along with support for 60Hz output from the Retina MacBook Pro.

Has anyone really ever noticed much difference with any of these betas? OSX 10.9 just runs pretty **** and sluggish no matter for me. A few random bugs come up or disappear with the betas but nothing major seems to be fixed or worked on. The fact that it's the same non descriptive list of "changes to" they give every time rather than specific changelogs gives me little hope to that much is actually changing, and that most of it is very very specific problems only few experience, or that is related to other big brands such as HP, DELL etc that they are fiddling with.
1) You shouldn't be noticing "big" or "major" changes in point fixes. These are not a move from, say, 10.8 to 10.9. A version release is when you, the end user, should see "big" changes.

2) If your Mavericks system is slow/sluggish - you should consider backing up your data via timemachine, do a fresh install, then import your data. Unless you have an ancient system that has a small amount of RAM, or possibly a failing HDD/SSD (and/or all three or some combination), or have borked your system folder in some way...Mavericks should be running like a champ for you. Mavericks, on my 4670K system, is ridiculously snappy...much more so than Windows which I, sadly, sometimes require.

Hahaha newbie only here but not elsewhere big up your mindset and respect people !

You are not obliged to trust it and try it neither, so love it or leave it peace of mind pls :)

This app helps to check the changes between installed build and the next one by date. That's it :)

it's easy to install i guess, i had no prob with !

Didn't really want to 'hurt' anybody, it's just not good advise to download a zipped file from an 'unknown' person.
You could be the nicest guy in the world, fact is, we don't know you, if you were a long time member, posting a lot we know you and trust you, since you are not I(we) won't download anything from you.
But, I do know OS X is fairly safe, no (known) viruses out in the open, I am not paranoid about it, but we just don't know you.
