Q: Lag in Typing in Yosemite's Mail w/ External Apple Keyboard

they've called in Scotty... problem must be with the warp core. sure he's "givin' it all he's got, but she can't take much more"

Kirk... you should have done that AGES ago

look forward to seeing what happens next. keep us posted, thanx!

I trust you've all seen this:

I've been a Mac guy and independent IT consultant for 21 years and I'm really, really sad to say that I couldn't agree more.

Kirk out

every version of every OS has problems. i hate this issue with mail, but other than that...yosemite's been great. fast, stable...what i want most from an OS. while i need this fixed, i would not trade the current OS for any previous OS (and in the overall scheme of things, 10.6.8 was pretty great)...

OK, but for me this is the only consistent bug I've seen in Yosemite, and I've been using it since July. I now have it installed on four Macs I help with. It's in daily use on three of those, getting work done. I've used Macs since 1988, and I think Yosemite is at least as good as any version I've ever used.

Most complaints I've read about Yosemite are sort of, like, 1: Apple added some functions from iOS (OMG!). 2: "I hate the flat look" or 3: "It's a mess." (No specific complaints.)

I'm sure there are some legitimate problems with certain software/hardware combinations, just not ones I happen to use. I'm not criticizing anyone who has a specific, verifiable problem that can legitimately be blamed on Yosemite. If you're one of those, please contact Apple.

Here's what the author of the article you linked to says about his own short rant:

I looked back at what I wrote with regret, guilt, and embarrassment.

Yes - saw that article just last night. I also have painfully agree. The downgrades to Numbers and Pages have been amazing in particular. Now I'm feeling like Outlook is outpacing Mail and Calendar, that Lightroom long ago outpaced (and now killed) Aperture, and that Excel and Word are progressing in ways that iWork is not.

I'm not abandoning any of these apps yet, because I know that the other side of the fence has it's own thistles hidden in the green grass. But I am missing that feeling of "Just Works" superiority I used to have.

funny, too, if you were to go back and look at any mac forum after any OS release; lots of complaints, issues. lots of 'why did they change this'. and the funniest part...six months in, people start clamoring for change: "where's the new stuff?" "cmon apple, give us some new features" etc. then, when the next OS hits, you've got people trying to get the 'old' features back, and the complaints start again. it's an endless cycle (and at least, entertaining)...

yes, at the top of the article is this: Update: I regret having published this.

But he's not saying his observations were wrong - he's just sad his name was included in something the press used to fan the flames of the "Apple is dead" naysayers. In my opinion he's just saving face.

"I handed the press more poorly written fuel to hamfistedly stab Apple with my name and reputation behind it. And my name will be on that forever."

"In my opinion he's just saving face." i think he's saying something different. anyway, it's all opinions. either way, am happy with yosemite overall. and will be ready for the good stuff/bad stuff with whatever comes next.

please keep us informed. i have the same typing lag. my cpu will show 87% idle but my system. and it happens even when mail is closed if imessenger is open. it gets better if they are both closed.

All right, I have a new wrinkle besides the lag, which incidentally seems to be getting worse:  on my 2011 11" MacBook Air, which started exhibiting the lag right away after the Yosemite upgrade, now sometimes when I hit the space bar, the cursor leaps BACK a space! Possibly lag-related, but man, does this ever make it impossible to make a correction. It's like the whole darn app is coming apart at the seams. Disgusting, is what it is.

I don't understand why there isn't a bigger hue and cry about this on the Internet or Mac websites. It's totally awful and absurd.

am again wondering what starts this; i was running yosemite (and numerous betas) for a long time before the lag showed up. meanwhile, that space bar thing seems part of the lag as well...and yeah, it IS a nightmare to make corrections. but seems a lot of 10.10 users don't have the lag (at least, LOL, not yet...)

Am observing the delay getting LONGER. Almost ten seconds now. This is unconscionable.

I mentioned this problem a page or two back, for me the space disappeared every time it was after a word with an apostrophe,  'don't like' becomes 'don'tlike'...

Have not been bothered by this ridiculous problem since I went back to Mavericks.
