Apple has continued its pattern of nearly-weekly seeds of OS X 10.5.7 builds to developers, this time releasing Build 9J47. World of Apple again publishes (http://news.worldofapple.com/archives/2009/04/11/apple-gives-developers-new-mac-os-x-1057-build-seed-notes/) the seed notes, revealing a continued decrease in the number of fixes since the previous seed (http://www.macrumors.com/2009/04/07/apple-seeds-os-x-10-5-7-build-9j44-to-developers/).Build 9J47 of Mac OS X 10.5.7 includes only three new fixes but Apple has also increased the number of focus areas in the build.

Mac OS X 10.5.7 entered developer testing in late February and developers have seen seven builds over the testing period.The inability to install the Safari 4 beta remains the only documented known issue, while the three fixes are related to the SystemLoginItems proprerty list, Ethernet on Mac Pros, and a CFURLCache compatibility issue. Apple has also added Help Viewer to the list of general focus areas upon which developers are asked to concentrate their testing.

Sounds like Apple really want to squash any last bugs in leopard before releasing SL. At least they don't leave those who forgo the SL upgrade with a stable system :)

Of course there are always bugs to be found :p I doubt Apple will get away with this as the last update for leopard.

Apple just can't win!

People complain that Apple is taking too long with their “fix updates."

If Apple hurries their “fix updates” if it's buggy then people would really complain then INCLUDING ME!

I would rather see Apple take their sweet time to improve 10.5.7 and make it REALLY stable.

To me, 10.5.6 is already stable. So let's see if Apple can make Leopard even more stable than it already is before Snow Leopard comes.

... my guess is that they don't really care too much. Aside from the new GUI stuff, which obviously does not depend on anything not available in 10.5.6 (duh!), the rest is WebKit, and its nightly builds run on 10.5.5 and probably even earlier releases, just with the old GUI.

They just seem to want to limit the distribution scope of the Safari beta.

*puts on conspiracy cap* Why would they want to limit the distribution of Safari, Apple wants in on the browser marketshare wars...

They darn well better be doing that! Snow Leopard is very likely to abandon a lot of older Apple computers that people are still using. If OS X is gonna stop supporting these still-in-use machines then Apple darn well better make sure that the final operating system they're able to run is as bug-free an OS as possible.

As its told, Safari 4 is just a Beta. I like it alot after I installed it finaly last friday. I will say though, maybe just maybe Apple is working on something with the final cut of Safari 4 that they will release with 10.5.7.

I will say that I would want 10.5.7 to be as stable as possible, especially now because of MS and there Bashing of Apple as of late. I really hope Apple will fire a good blow to MS and take some more market share away from MS....

Damn you Safari 4. Holding everyone up. :mad:

I think the reason why they're not allowing devs to install the Safari 4 Beta on 10.5.7 is that, probably, the final 10.5.7 will be released alongside the final Safari 4. So there's really no use in testing the Beta with 10.5.7.

I expect there will be at least one and probably two more updates before Snow Leopard's release. Maybe more, if it is delayed beyond September.

I think Apple's taking its time because, as many people have stated, 10.5.6 is pretty darn stable. It's not like this patch is urgently needed.

So they can afford to wait and tie it in with some other announcement - probably the full version of Safari 4.

Maybe we need to consider that Apple is working on another Safari betathat kills some of the bugs in Safari. I have the beta istalled and frankly it has problems to the point that I often run Firefox.

I've seen things such as hang ups, refusals to reload a page to a number of other glitches. Safari simply isn't ready for prime time. It is what one would expect from a beta but hopefully we will have a new beta with the next update.

I like some of Safaris features like zoom, I just hope they smooth it out in the next beta. That is the response to a pinch on my MBPs track pad is way to course. Old age gas made that zoom capability very important. Some of the other features are nice too, so let's hope that a final stable isn't far off.

Exactly. I consider 10.x.6 or higher that Apple has gotten pretty much all of the major bugs out of the OS.

Now just let Apple take their time to make Leopard as stable and bug free as possible before Snow Leopard comes out.

Especially If Snow Leopard costs the usual $129. To me Snow Leopard just isn't worth $129 for just mainly “under the hood” changes that mainly effects computer programmers. Well I'm not a computer programmer.

To be perfectly honest, I'm more than satisfied with 10.5.6. It's very stable and pretty much bug free if you ask me.

PPCs are still very viable computers. My main machines are current, but I have a G3 and a couple G4s that still get regular use. There great to have around for things that don't need the latest and greatest software, graphics, etc.

Of course Apple is not interested in peoples legacy collections, but much like 10.4.11, I am sure Apple will work out the bugs, even continue to update 10.5 after the release of SL, for those using the PPCs.

I question Apple on some things, but this I think is rather cut and dry. I mean if MS can release SP3 for XP after Vista came out then Apple can still support 10.5 for the PPC crowd.

I was just wondering if we had any information/speculation as to what would be addressed with the next update? I'm fairly happy with 10.5.6. It's not perfect, but it has been pretty stable for me. Just wanting to know what I should be looking forward to! :)

It's unlikely that Apple will change their current policy of issuing only security updates for the previous OS release. IMO the main reason Apple is not carrying PPC support forward is to avoid the cost of testing and support resources for it. There's not much chance they'll want to spend much on those resources for 10.5 after 10.6 comes out.

Agreed - and that's why it's so important for Apple to make sure that the final version of OS X for PPC machines is as stable and bug-free as possible. Hopefully Apple will hold up their end of the bargain with the customers and deliver a great final PPC version of OS X.

Apple was still selling PPC macs as recently as august 2006. That's long ago enough that it's reasonable that they can't run the latest OS, but it is not reasonable to expect people are going to stop using their 3 year old machines altogether. So Apple better make sure the final PPC version of OS X is stable and bug-free.

Oh man, I'm so glad somebody else was having this issue! I thought the GPU on my Mac Pro was wonky and I was fretting about having to get it swapped out. I even uninstalled the Beta on here and went back to 3.2.1.

Not sure if those bugs you experience are in the GUI or in WebKit. But as for WebKit bugs, you should try installing a nightly from webkit.org. It will look exactly the same as before except being called WebKit and having a blue icon. But some bugs will be gone, such as the one that prevents you from logging into zenbe.com.

You're not a computer programmer, but you run computer programs. So if those under-the-hood changes are things that programmers like, then the apps you want to run will use them which means you'll have to run 10.6.

No, we “don't have to” run 10.6 to run applications. What, do you think that magically ever application will quit running on every other OS when Snow Leopard comes out?

The only thing that Snow Leopard will do is to make the new applications easier to build for computer programmers. Unless they make some kind of new “just live without” application, I think I'll wait until 10.7.

Snow Leopard's innovations are primarily about increasing performance on new and future Mac platforms. For the system you have now 10.5 will be fine. Those customers who move to new systems with multi-core processors and more graphics power will benefit from 10.6.

Exactly Eric S.

I just have '06 iMac with a single cord and a '07 MBP with C2D. My computers will be just fine with Leopard for few more years.

I just don't see of spending $129 for a OS basically will make my computers a little bit faster if even that.

Apple cannot get this our quick enough for me. I admin 150+ computers in a school district, some teachers have admin rights for programs they use. They installed 10.5.6, and now are experiencing lockups on login, and kernel panics on logout. Yes, I can re-image to 10.5.5, but a lot of the computers are customized with software specific to the classes they are teaching... Really, 10.5.6 has became a huge pain for me..... 10.5.7 hurry up!!!!

Then don't upgrade. I'd say that 10.5 will become the new 'lowest common denominator' for future software so even if you choose not to upgrade - you'll still receive software for the next couple of years.

I for one welcome the new technologies because hopefully what it will mean is applications will take advantage of those new features. Under the hood changes can result in user visible improvements - don't try and claim that you can change the operating system and there is no noticeable improvement to the end user.

And you know what? Apple ][e and ][gs systems are still functional today.

I'm sorry, but while I agree that the hardware still works and can be repurposed for other tasks, the truth of the matter is that the current generation of x86 tech so utterly outclasses where the PPC architecture leaves off that one would have to be daft not to upgrade.

I'd say that 10.5 will become the new 'lowest common denominator' for future software so even if you choose not to upgrade - you'll still receive software for the next couple of years.
Yeah, that will probably be the case, kind of like how Win98SE became the minimum OS requirement for years and years. Of course, the issue is that there promises to be so many underpinnings improvements introduced with Snow Leopard that it may become the LCD in fairly short order. It won't happen overnight, but I'll bet that, within 18-24 months, you'll find enough migration by developers that it'll become worth most people's while to do the upgrade.

I'm claiming just that. Like Eric S. said Snow Leopard is for future Macs that will have more multiple cord processing and more powerful graphics cards.

My iMac is a first generation of Intel that Apple had put into their Macs. It's not even a C2D.

My MPB is a C2D, so maybe I could see some speed increase on my laptop with SL. Again though, it's just not worth the $129 to maybe see some speed increase with my laptop.

Your iMac is still a dual core and will still reap the benefits of an operating system better tuned for multicore performance. As for OpenCL; I am not too sure whether your video card is supported but I see no reason why you shouldn't experience a performance boost there.

Your iMac is still a dual core and will still reap the benefits of an operating system better tuned for multicore performance.

Dual-cores have been out for years and it's likely the OS is already highly optimized for them. I doubt any performance gain will be noticeable with Snow Leopard.

As for OpenCL; I am not too sure whether your video card is supported but I see no reason why you shouldn't experience a performance boost there.

If it's not supported, why would you expect any performance boost?

Dual-cores have been out for years and it's likely the OS is already highly optimized for them. I doubt any performance gain will be noticeable with Snow Leopard.

I doubt it. Microsoft's own operating system finally started to be properly optimised for multicore designs in Windows 7 although there were improvements in Windows Vista. Hyperthreading wasn't optimised for until many years after it was released due to the OS not being able to differentiate between a virtual and real extra processor.

If it's not supported, why would you expect any performance boost?

I'm assuming that Apple or some third party will develop CODEC's that will speed up compression by offloading it to the GPU.

Eric S.

I doubt it. Microsoft's own operating system finally started to be properly optimised for multicore designs in Windows 7 although there were improvements in Windows Vista.

But we're talking about two cores, not multicores. It's a lot easier to keep two cores saturated than four or eight, or more. I suspect that the whole reason that Grand Central is needed is that Apple's current scheduling algorithm is fine for two cores but doesn't scale well when more are involved.

Hyperthreading wasn't optimised for until many years after it was released due to the OS not being able to differentiate between a virtual and real extra processor.

C2Ds don't use hyperthreading, so I'm not sure what that has to do with it.

I'm assuming that Apple or some third party will develop CODEC's that will speed up compression by offloading it to the GPU.

Now it's my turn to doubt. ;)

Dual cores have been extinct for years, SL just wasn't build for them.

Dual cores were only built like for nine months or so. For me, I was so frustrated because I got my iMac in June of '06 and Apple started to put in C2D's in September of that year.

If SL comes out this September, that also would be the three year anniversary when Apple dumped the dual cores.

So sorry, all the dual cores can do is run SL, but you're just not going to see any performance boosts.

Dual cores were only built like for nine months or so. For me, I was so frustrated because I got my iMac in June of '06 and Apple started to put in C2D's in September of that year.

If SL comes out this September, that also would be the three year anniversary when Apple dumped the dual cores.

I think you are talking about the Core Duo vs. the Core 2 Duo. These are both dual-core processors. The difference is that the Core Duo is 32-bit, the Core 2 Duo is 64-bit.

Exactly Eric S. SL just isn't made to help the 32-bit much.

But we're talking about two cores, not multicores. It's a lot easier to keep two cores saturated than four or eight, or more. I suspect that the whole reason that Grand Central is needed is that Apple's current scheduling algorithm is fine for two cores but doesn't scale well when more are involved.

C2Ds don't use hyperthreading, so I'm not sure what that has to do with it.

Now it's my turn to doubt. ;)

Future Intel CPU's will include the re-introduction of hyperthreading - there are also many P4 users out there that have hyperthreading; but hey, abusing and being rude to me is alot easier than addressing the issue.

Oh, here is the article where Microsoft is finally optimising their operating system for hyperthreading:

If you spent time reading what I wrote, I used the hyperthreading issue as an example of how there is a lag between new hardware features and Windows being optimised for it.

Yes I know that, and that Nehalems use hyperthreading.

Sorry if you took it as being rude. I didn't mean to be.

OK, I probably missed your point. Sorry.
