OS X 10.8 Mountain Lion Developer Preview 2 Seeded to Developers

[AidenShaw]

That's because it's basically Vista with eye candy.

It isn't necessary to "throw the baby out with the bath water" when you release an innovative new UI.

For example, when you run terminal in Apple OSX, you're basically running the 1970's UNIX UI. (and that's a good thing)

I have an older Tascam fw1884 FireWire sound card and controller.
Discontinued and only have 32 bit drivers.
Dp1 I was able to boot in 32 bit mode!
Dp 2 I am unable to boot in 32bit mode, only 64 bit mode!
I held down the 3 and 2 keys while booting.
Is there a way to boot DP 2 in 32 bit?
The sound card will not sync

Just be cause he disagrees with you (and almost everybody else) doesn't mean s/he deserves to be "dealt with". That's the essence of freedom of expression. How about we "deal" with all those who took the bait and disagreed with him/her instead? Oh no... that would be "unfair"...

Firstly, I made no comment for him to disagree with me about. I merely made reference to the fact that every other review is opposite to his comments.
Secondly, freedom of expression doesn't include "hate speech"
Thirdly, when a forum is created a community evolves based on the ideology of people sharing information and helping one another, with opinions given based on experience or facts.
Fourthly, people who did disagree with his comments are doing the noble work of bringing to attention the ill-will of such a person who makes these kind of comments. That is to be applauded.

Is there a new version of Safari in DP2?
DP1 has Version 5.2 (7535.18.5)

 

[edgarf28]

yes, it has now Safari 5.2 (8536.2.3)
And it feels (really) snappier!

 

[WeegieMac]

DP2 is definitely slightly quicker than DP1 on my iMac, with the improved animations noticed in DP1 retained. Amazingly stable too, and looking good. The new Safari build screams, and the new loading bar is surprisingly "pleasing".

Model iMac8,1.
Intel Core 2 Duo 2.4GHz.
4GB DDR2 800MHz.
ATI Radeon HD 2400 128mb.

Thats actually a really good thing.

Look at what legacy support does to Windows : /

While I very much agree with you, I wish Apple would open up virtualization and allow VM Ware / Parallels / etc... so that Snow Leopard (and even older versions of Mac OS ) could run in a virtual machine on a Mac. I'd also love to see them either license and/or open source their Rosetta code.

 

[AidenShaw]

Rosetta belongs to IBM, not Apple

Rosetta was developed by Transitive, a company purchased by IBM.

I thought Apple bought the Rosetta technology from them, did they just license it and optimize it? Either way, if no one is planning on using [profiting] it then it'd be nice to see it put out in the open. I realize this is unlikely, but that doesn't mean I wouldn't like to see it.

Licensed....

This technology was also licensed by Apple Computer in its transition from PowerPC to Intel (x86) CPUs, starting in 2006.[1] Apple marketed this technology as "Rosetta".​

This story also explains what IBM is doing with it (running x86 on POWER - LOL).

It's also unclear to what extent Apple would have optimized Transitive's code. Apple could certainly have worked with Transitive to provide para-virtualized assists in Apple's code to improve performance, but it's not that common for the core source code to be shared with the licensee.

 

[seclusion]

Can't boot into 32 bit mode, making my Tascam FW 1884 sound card unusable.

So on to craigslist it goes

 

[DaBlakkBear]

Truth hurts, doesn't it?

Uh No!

I wonder if the new Safari build will be made available for use on Lion like the previous one was....

Interesting, thank you for taking the time to post that. I must say I like Apple's name for their implementation of the technology (Rosetta) better than IBM's (PowerVM Lx86) but then again, I may be a bit biased.

Not ure, but I wish the beta that is in ML was available for Lion right now, I'd love to give it a try even if it became ML only for actual release (like messages is, I think).

 

[twoodcc]

looking forward to 10.8!

 

[cjmillsnun]

The GM could be the closest thing considered to a beta but we aren't there yet.

A GM is not close to a Beta at all. GM is Golden Master. It IS the release version.

----------

FUD.

Windows 8 has the same hardware requirements as Vista Home Premium - so we're talking about support on systems from fall 2006, more than 5 years.

And it breaks little legacy support - the desktop and all of the APIs are still there (at least on x86/x64 systems - I'd expect much of the legacy support to be dropped for ARM tablet-based systems).

And it runs like crap on a system that runs Win 7 just fine.

 

[KALLT]

Now, turning to the matter itself, consider this: Apple is enforcing Sandboxing as a pre-requisite for AppStore status. Simultaneously it is allowing Notification Center access to AppStore apps only. This means they've very consciously set up a set of incentives to offset the onus of complying to the Sandboxing policies.

If you think about it, all-and-sundry access to the Notification Center could be extraordinarily annoying. Think of the potential for spamming, how annoying it'd be if a small random application you downloaded from Wherever could serve as a conduit from some third-party Spamhaus to your Notification Center, (at worst) inundating you with Viagra spam or (at best) acting as a Groupcon shrill.

I don’t find this very convincing. First, I expect that Apple is going to introduce preferences for the Notification Centre just as the iOS version has, if it has not done so already. This means that users can customise and restrict access to the Centre for certain apps. Second, if that option would not be available, users would still be able to simply remove the app altogether. Such apps will hardly be popular. I therefore cannot imagine that abuse is a good reason to restrict access to the Notification Centre.

What I find more problematic is that Apple seems to abuse its position as both the operator of the App Store and the owner and developer of OS X by limiting certain OS features to App Store apps. The result is that developers will at some point be forced to use the App Store to distribute their apps in order to fully benefit from all of the features. This makes alternative ways of distribution less attractive. We do have to keep in mind that there are many reasons why developers are not using the App Store right now, e.g. technical limits, Apple’s arbitrary approval policy, unreasonable rules, and so forth. There are many interests at stake here. The Notification Centre could be just the first App Store exclusive feature, what else is going to follow in the feature? I think this is a sad development and it seems to support the fears that OS X is perhaps indeed slowly becoming a locked-down OS.

Any thoughts on release date or pricing? Or things like if our Macs with the "lion install partition" or whatever will be updated to? I was very happy about ML. Months back I was bothered about some weird inconsistencies (things like iCal vs Calendar, or Contacts vs Address Book), and am pleasantly surprised to see Apple making these changes.

 

[AidenShaw]

I haven't seen that reported on any of the Consumer Preview reviews, nor has it been my experience on a Core i7 and a ULV 1.4 GHz Core 2 Duo.

Links?

 

[chrono1081]

A GM is not close to a Beta at all. GM is Golden Master. It IS the release version.

While I generally agree with this, it isn't always the case. There have been cases with multiple GM seeds due to errors found in the first GM seed. I believe iOS 4 had this issue (I don't save my past SDK's so I can't look to be sure).

Even though you are correct that the GM is usually the release version, I was indicating it was the closest to a beta since Apple doesn't release public betas only developer previews of their desktop OSs.

I have noticed this too. We've been testing 8 at work and it doesn't perform the same as 7 by a longshot.

Some specifics would be useful.

Also, note that Microsoft's beta builds are instrumented debug builds that are doing tons of extra things (like partially optimized code that does heap poisoning and checking on every new/malloc/free operation).

So, it's expected that precise performance testing of production Win7 vs debug Win8 will favor Win7 - but by and large unless you're hitting an edge condition few reports claim problems with Win8 performance.

What's the performance difference on what applications?

I actually can't give specifics because I"d get fired in a heartbeat if I ever took any of our reports outside of work but its big enough that it isn't just a developer build vs a release build issue.

As for applications we test custom in house applications that have been optimized for the newer OS (We can't really test anything mainstream since those applications haven't had the opportunity to be compatible yet).

When we tested Vista vs the beta of 7, the beta of 7 outperformed Vista. Its definitely not the case this time around.

If it doesn't change by release our company won't be upgrading to 8.

Beta, I know, but stupid! Try to use a picture from you Image Folder as background. Now, restart the system. See? The system comes back with default galaxy background. It does not like your pictures! And there is more. Try to send trash to Trash...Oh God you'll have to force quite Finder. Beta...I know.

I hope you're filing bug reports for all those!

Considering the reception of win8 CP there might not be all that much competition...

I think that there needs to be more competition in this area, if win8 doesn't take off then apple might have free reign. We couldn't have them getting sloppy now could we.

HA! From what I have seen , if Win8 takes off, I will grow wings! I think
it is the new Vista, and and an attempt to copy Apple OSX, IOS, and Android all in one!...I would not touch that thing with any pole!

Speaking of Mtn Lion, judging from past releases....try as they will, some apps will be broken and require updates! JMHO! As someone here said...."a lot will change under the hood"

Right now I am quite happy with Lion 10.7.3; and it runs very fast on my mid 2011 iMac! (TG) No crashes, panics or other wise!
