Yosemite ???
 

Well, it's been a couple of days that the new Mac OS has been in the wild ...

Not much in the media about it.

I'm following SOP and will be waiting another week, or so, before updating my iMac/Macbook but curious to hear of any experiences from other PPRuNers.

Good? Bad? Indifferent?

Yosemite ???
 

Updated my mbp 2010 with no problems. Actually running a little faster than under mavericks for now.
Quite happy

I'm thinking about upgrading on the weekend.

I think it should be a pretty solid upgrade, and the iOS integration should be interesting to see.

I risked Yosemite last Saturday morning.
Best update ever, I started with OS 6, only the Wacom driver needed renewing.
To my surprise everything really is running faster, best I have seen on this MacBook Pro 6,1.
The green button function has changed, but cntrl + button does what used to be just button to fill screen.

I've installed Yosemite on our MacBook Air, Mac mini and iMac, all without a hitch. I personally think this is the best iteration of OS X that Apple has ever done. All 3 machines are working just fine. And the iOS integration with out iPod Touch(s), Ipads and iPhones is superb.

I've installed it and generally very happy with it.

The much-vaunted handoff is not very reliable so far and only works sporadically. I daresay that will be sorted out soon. But when it works, it is excellent - really cool to be able to answer a call from computer if you've left the mobile downstairs, or reply to texts direct from computer instead of messing around on iphone keyboard. The new iCloud drive is a big improvement too.

I guess the reason that there has not been much reaction in the press is that generally it is very good.

Thanks very much everyone, I'll likely do it over the weekend.

I installed it on my iMac and it runs perfectly, better than before and a superb OS.

However I put it on my 2010 Macbook Pro and it's now running so slowly and badly it's unusable. Currently investigating!

Some general (not Yosemite specific) troubleshooting ideas here.....

I read somewhere that although being designed for new and newer steeds, the OS can operate on older computers, but 'might' be a bit heavy on the RAM, with a figure of 2GB's needed, but 4GB's being recommended.

I deployed Mavericks to 5 Macs last week, trouble-free apart from some printing issues.
Good upgrade. Finder in particular is much faster at accessing Windows SMB fileshares :cool:

Out of interest, how does it compare to DAVE or haven't you used that ?

I have an iPhone that cannot be upgraded to iOS8, I'm guessing that none of these bells and whistles will apply ...

Well, there are various other changes in Yosemite, but you're probably right that many (not all) of the major new features relate to integration with iOS.

So although it would be worthwhile you upgrading eventually, you could happily wait a few months if you like...

Haven't used DAVE, sorry Mix...

Whilst passing an Apple Store today, I decided to dive in and ask a quick question from one of the bods there. I started my spiel and then the bloke gave me a strange look and said " I might be wearing a blue tee shirt, but I don't work here!"….He was wearing a perfect pantone matched blue tee shirt, just that his said 'Greece' and all the others had an Apple logo on theirs :hmm::} Anyway, when I did find someone to ask about upgrading to Yosemite on an older steed, they said that whilst a bit more engrossing than previous OS's, one could "upgrade the firmware to accept more RAM" and said that they had a 2ghz MacBook that they had done this to and all was well with Yosemite….I'm intrigued, can you upgrade firmware on a mac ?

Are you sure you understood them correctly ? Maybe they were just saying you could open it up and put more RAM in there ?

You can't just magically flash a computer motherboard (mac or PC) to accept more RAM ... the amount of RAM supported will depend on a combination of CPU, motherboard and operating system constraints....so its not just limited to some arbitrary number picked out of a hat by the manufacturer, its determined by system engineering constraints.

Yes you can upgrade firmware on a Mac, and Apple have in the past released such upgrades for various reasons ranging from Bluetooth issues to sleep problems.... but AFAIK there have never been any updates that magically increase the RAM because that's simply not possible in system engineering terms.

I'd be inclined to agree with you mr mixture. Perhaps they meant that the max RAM recommended by Apple at the time could, when component upgrades allowed be increased without detrimental effects (but obviously limited to technical limitations) ? Maybe like the electronic limiters on modern cars that can be 'hacked' to allow a larger range of performance to those so inclined ?

SpringHeeledJack,

Well, to be honest I've never really put much thought into RAM limits until this question came up !

I've always just understood RAM limits to be a predominantly hardware limited thing.... combined with the occasional software limit (e.g. 32 vs 64-bit, and Microsoft/VMWare licensing limits).

Which is why I would be surprised if you can do anything to something that's as deeply engrained onto a motherboard and CPU (northbridge memory controller hub) .... but if someone lurks here who's spent time system engineering for a modern manufacturer (not really interested in tales from the computing dark ages) , I'd be happy to be shown evidence to the contrary !

I guess you may be onto something that larger RAM modules may not have existed as commonly "back then" when Apple were designing those models as they do now ? But I still think its more of a CPU/motherboard hard limit than what Apple were able to test with ?

In the mean time I'm going to spend a couple of minutes on Googoo to see if any definitive looking answers pop up ....

I'm running a 2011 Macbook Pro with 2.7 mhz and 8 meg of ram. I would say that I'm seeing a lot more "wait wheels" than previously. I do like some of the changes such as discrete browsing, but its coming at the price of a slower machine.
