Why does Yosemite slow Imac as well as MacBook Air?? Any Idea for a solution??

I have installed Yosemite on my iMac as well as on my MacBook Air.
Both now boot very very slow.
I regard this as a big disadvantage.
Does Apple have a solution?
If if would have known of this problem in advance I wouldn't have updated on Yosemite!!

As far as I've observed the long boot times on both machines running now Yosemite is the only major problem.
However, trying to delete an additional user on the iMac (under Yosemite) lead to a frozen iMac. So the only solution was to finally switch of the iMac manually from power supply and start it again. However, then it worked.

Why does my music stop playing on my macbook air

I have a macbook air with GB memory and 128GB storage. I"m using Yosemite X OS 10.1.1
Whenever I play music from either my iTunes or Spotify library the music stops after about an hour and the macbook goes into sleep mode. This does not happen on my iPad?
I've tried troubleshooting via system preferences as I thought It might be to do with the screen or energy saver or a limiting function associated with the software. I've looked on both apple and spottily support sites and spoken to friends who have similar products but do not experience the same problem.
I'd be grateful for any ideas

Hello rjsw15,
Thank you for visiting Apple Support Communities.
It is normal for your display to turn off while music is playing on your MacBook Pro, but it is unexpected that the computer would go to sleep.
In your case, I'd recommend resetting the System Management Controller (SMC) as a troubleshooting step to try first. This step helps in a variety of cases, including:
The computer sleeps or shuts down unexpectedly.
You can find more information and the steps to reset the SMC on your MacBook Air at this link:

I am having trouble using reverb of any kind; it does not sound natural, but rather "pixilated." Does anyone have any ideas for a solution? I have used Silververb and Space Designer and am having the same problem...

I am using Logic Pro 9 with two MXL 990 microphones in my piano and a Rode NT1A for vocals. I have tried recording with added reverb and keeping getting not a natural reverb sound, but a rather "pixilated" one that does not sound natural. Does anyone have any ideas on how to solve this issue? I have tried using Silververb and Space Designer, and both result in the same problems. Thank you!

This is asking for the impossible! It does not sound natural because maybe it isn't and in judging so whats your reference anyway. If you are in dire need of some natural sounding room you can go and record it yourself. But even then, the chances that it sounds like you imagined it, are very slim.
There are very decent sounding reverberation plugins, based on artificial reverb generators or convolution-style, the last one is said to sound more 'natural' then the first one. Be it as it maybe, it really is like cooking food. You got all the ingredients for this delicious taste at hand and believe it or not to reach a satisfying result this is not enough, because if you do not mix the ingredients in the right proportion you will end up with a different dish you thought you'll get. This is exactly the same when one would mix audio, I dare say.
So treat yourself to some good ingredients and the rest is up to you, namely: taste and experience!
And looking at some of my past music productions I always find the same plugins for the 'ambient' task:
Altiverb by Audio Ease when I have acoustic ensembles (classical music mostly), the Sony Oxford Reverb in studio productions, Bricasti when I have to deal with drums and MMultiBandReverb from MeldaProduction for all-round stuff. Thats the base I start from, after that I can end up with dozen Reverb plugins which basically all are doing the same thing but just in a tiny different way.

Why won't my iMac find my new MacBook on the network for Migration?

My older iMac (7,1) can't find my new MacBook Pro on the network. I've tried two different WiFi networks. I've ensured both machines are current in their SW. I can't use Ethernet because I didn't buy the Thunderbolt to Ethernet connector. The MacBook sees the iMac, but the iMac just keeps searching and after a while the MacBook displays a message that the iMac is not responding.
I believe I'm following the Migration Assistant directions properly, starting the app on the iMac and selecting migrate to a Mac, and then starting Migration Assistant on the MacBook and selecting migrate from a Mac or PC.
It used to be that I could connect the two via FireWire and start up the older Mac while holding down the "t" key and the newer machine would see the older machine as a disk drive. Without FireWire on the new machine could I use a USB connection the same way?

Lessons Learned:
Thunderbolt to FireWire is only for FireWire 800 so doesn't help connect to older FireWire 400 disks. (Apple Store employee says there is a FireWire 800 to FireWire 400 converter, they just didn't have it in stock.) My iMac has a FireWire 800 port, but I didin't have a FireWire 800 cable. (I'm opposed to buying one time use things, like the Thunderbolt to FireWire adapter, FireWire 800 to 400 adapter, or a FireWire 800 cable.)
Be sure to pay attention to migration direction. You can migrate either direction, but you probably don't want to migrate from a new machine to an old one.
If you have the same user id on both machine you cannot migrate into the user id you're logged into on the new machine. Might be better to first create a dummy id on the new machine, migrate all old id's over, and then delete the dummy id. Obviously I didn't do this.
If you have a wireless router with multiple ethernet ports you can connect the two machines to the router, ignore the wireless network, and connect via ethernet. I could not connect the two machines just running an ethernet cable between the two. (I think someone suggested that.)

Why does the wifi keep disconnecting on the Macbook Air (Bought September 2013) ?

Is this only my MacBook Air, or is it with everyones. The wifi keeps getting disconnected and i would have to switch off and then switch on the wifi in order to reconnect.

Hi Ettedos,
Thanks for visiting Apple Support Communities.
It sounds like you're seeing unexpected behavior on your MacBook Air.
I'd recommend starting with the Wireless Diagnostic built into Mavericks:
OS X Mountain Lion v10.8.4 or later
Use the Wireless Diagnostics application included with OS X Mountain Lion v10.8.4 and later to identify and resolve Wi-Fi issues. For further information, please see About Wireless Diagnostics.

Why does our new iMac down load speed so slow (1.99) being right next to router. Our hp laptop 30 ft away ran at 13.50.

Why does our new imac download speed so slow (1.99) being right next to the router? Our HP laptop 30 ft away is running at (13.50), and our old HP desk top connected to highspeed is at (33.10).

You are surprised that Mac OS X 10.7 is running on hardware that Apple officially supports and says it will run on? I find your logic unbelievably falwed.
Not a single problem I've mentioned would be caused by "slow" CPU or "little" RAM. How does iPhoto not bringing up the file dialog box have anything even remotely to do with the speed of the CPU or the quantity of RAM? If what you say is true, then yes, performance would be bad, but it wouldn't be selectively bad. I stated that apps such as Reason 5 run perfectly fine, even really well. I can load 30-50 racks and synths and not even reach 50% of CPU utilization, Reason never freezes, etc. DVD playback never freezes as well!! Your logic is horrendously flawed, it seems you don't know much about computer architecture Thus, unfortunately, your reply was of absolutely no help, sorry.
p.s. the external disk spin up problem freezing up the entire graphical interface also has nothing to do with either my CPU/RAM or the OS version I'm running. It is a known crippleware factor of Mac OS X that at least a thousand people are complaining about online and Apple has done nothing about!

Why does my new iMac keep freezing for no apparent reason?

Why does my new iMac keep freezing? This usually happens when it is not being used and is particularly frustrating when I do need to use it and ahve to switch off and then on again and wait for it to reboot.
I am not computer literate so keep any answers as simple and idiot friendly as possible. I treat it like a car. If I put in the key and turn the ignition on and the enginesprings into life I am content. If not.............. well!

In order to provide any help we need to understand a little bit more about the problem you are experiencing.
You indicated the issue occurs when the sytem is not being used. Does this mean that you stop working on the system and the system 'goes to sleep' where the screen goes black, but when you need to wake it back up by pressing keys on the keyboard or clicking the mouse the system doesn't wake back up? To test for this issue open the System Preferences and click on the Energy Saver preferences. See the 'Computer Sleep' slider to the far right 'Never' setting. You can set the 'Display sleep' setting to any number you prefer. With these settings see if the issue still occurs and let us know the results. If it resolves the issue then give Apple a call and let them know you are unable to wake the system when it goes to sleep. You shouldn't be having that issue.

What is cookies.sqlite and why does it slow the start up of mozilla by a minute or so. I found it and deleted it,fixed the problem, but it reappears eveery time I restart mozilla.

what is cookies.sqlite and why does it slow the start up of mozilla by a minute or so. I found it and deleted it,fixed the problem, but it reappears every time I restart mozilla.

AVG reports these sqlite cookies each time firefox starts. they usually belong to tribalfusion or some other tracker. How do I block them in the first place. I thought firefox is a safe browser. Did not have this problem until I upgraded to 3.6.

When I try to export photos from iPhoto, why does it truncate the title I have given the photo? For example, I have labeled it 2013RoxyCarousel. When saved to desktop, it reads 2013. The rest is omitted.

iPhoto 7.1.5.
I chose these settings:

Include title and keywords (checked)

I guess that is what you meant. Thanks for replying.

My imac 27 ``- superdrive accepts and burns CDs and DVDs but no program DVDs. Does anybody has the same problem - or an idea for a solution of that problem?

Hello imac-users, my problem is: the superdrive accepts normal CDs, DVDs and is also burning them - for example music from itunes. But today I inserted 2 program DVDs - photoshop elements / Adobe and ms office 2011 for mac - and the superdrive does not accept them. After some seconds of running and noise, the DVDs are ejected - also no icon for the DVD on the desctop. So I think, it has something to do with OS X and not with the superdrive. Does anybody having the same problem - and an idea for a solution?

Not using any mouse pad, I have a very smooth desktop. But I just tried to use a sheet of A4 printing paper, but no result, the problem persisted.
Someone on this forum suggested, that USB3 may interfere with the magic mouse.
I have 2 LaCie HDD's about 70 cm away from the mouse, I use them on Thunderbolt. But in operation or not - the result is the same, the mouse plays up! Just now I was clicking the desktop and the mouse created a new folder!!
Thanks for the advice, Bee
Cheers, Gerd

Why does my IPad put I's, which is not a word, for the word "is"?

Why does my IPad put I's, which is not a word, for the word "is"? This I's driving me crazy!

You probably typed an error that got accepted in your keyboard dictionary. To get rid of it, reset your keyboard dictionary. Go to Settings > General > Reset > Reset Keyboard Dictionary. This resets all the suggestions you’ve made to the dictionary.
To accept or reject dictionary suggestions:
To reject the suggested word, finish typing the word as you want it, then tap the suggestion to dismiss it before typing anything else. Each time you reject a suggestion for the same word, iPad becomes more likely to accept your word.
To use the suggested word, type a space, punctuation mark, or return character.

Installed iOS6 on my 3GS phone. The maps app works well, but does not give spoken turn by turn directions.
Any ideas on how to fix this?

Go to http://www.apple.com/ios/maps/ and look at the bottom: Turn-by-turn navigation is available only on iPhone 4S, iPhone 5, and iPad 2 or later with cellular data capability. Flyover is available only on iPhone 4S, iPhone 5, iPad 2 or later, and iPod touch (5th generation). Cellular data charges may apply.
You can always use the WAZE app like I do.
