OS X Lion - will it slow down my Macbook Air?

Does anyone know if the new OS X Lion will slow down the perfromance of my Macbook Air which has the following specifications:
2GB, 1,86 GHZ
or is it better to stick with the OS X 10.6.8?
I read today that Lion is having an impact on machines which have processors less than 2GHZ and are only equipped with 2GB
Thank you.

I did an inplace upgrade on my Gen1 13" 80GB IDE MBA model.
Whilst it was always an overheater of playing anything flash or full screen video I find the performance has not changed since my upgrade.
I am a light user.
Internet/cloud documents/messenger & remote desktop/VPN
The boot time was always poor for my MBA, but that said, how often do we reboot them
Ever since day one, I've never been able to run imovie/CS3 as it would throttle my MBA, but Lion installed fine, even when my HDD was 90% full.

I have a macbook 2009 2gb model. If i upgrade to mountain lion will it slow down the laptop?

I have a mac book, 2gb 2009 model. I am thinking of upgrading the system to mountain lion but recently did the ame thing on my work's desktop mac and I find the system is slightly slower. Will it make my macbook slower doing this. Currently I'm on Mac OS X 10.6.8. Thanks

i've been running mountain lion on my white unibody 2gb ram macbook since launch. it is possible and it works, but i just upgraded to 4gb's yesterday and i can tell a difference in the os. its not dramitically faster like an ssd would be, but its definitely snappier and smoother.
i got my 4gb ram at owc for 32 dollars shipped and it was very easy to install.

Will it slow down Mac book aluminium with Mountain lion?

I m very interested with new os of Mountain Lion and i consider to upgrade it. But I really concren about will it slow down my current Mac Book Aluminium? As I have upgraded to 4GB RAM.

You'll need to wait until it's released for the various groups that benchmark new systems to run the comparison tests. Macworld.com is pretty good about that.

I have an older mac w/LION 10.7.5 - if I upgrade to Mountain Lion 10.8, will it slow down my computer significantly?

I have an older IMAC - purchased in 2007. Works well. I have LION iOS 10.7.5 and want to upgrade to Mountain Lion 10.8. Will it slow down my computer? If so, how much?

Read the following technical specification
This will tell you what facilities your computer needs to be upgraded to Mountain Lion.
Pay particular attention to the amount of RAM. Apple says you need 2GB, most people here would recommend 4GB.
When you are satisfied you are equipped, you will need to use App store to buy the download ... and away you go.

I'm about to buy a 27" i-Mac. I would like to connect my 30" Cinema Display to it as a second monitor. What will I need to do that? Will this slow down the overal performance?

I'm about to buy a 27" i-Mac. I would like to connect my 30" Cinema Display to it as a second monitor. What will I need to do that? Will this slow down the overall performance?

The new iMacs do not come with a MiniDisplayPort, they have Thunderbolt, so unless you are talking about purchasing one of the previous generation iMacs such as this refurbished model in the online Apple store, it won't work. And yes, if you are going to get the full range of video resolutions you will need the Dual-Link version.
For details see the store's web page on the Dual-Link display adapter.

Hi, I am using an old PC P2 450Mhz, 256 MB Ram. Is ver 3.6.16 ok for my system or will it slow down the system? Thanks

Hi, I am using an old PC P2 450Mhz, 256 MB Ram. Is ver 3.6.16 ok for my system or will it slow down the system? NODD is the anti-virus. I am not happy with IE or goolge as these are taking too much space. Thanks

The system requirements for Firefox 3.6 are:
* Pentium 233 MHz (Recommended: Pentium 500 MHz or greater)
* 64 MB RAM (Recommended: 128 MB RAM or greater)
You exceed the minimum and are just short of the recommended processor. It should run OK but the only way to tell will be to try using it. Note that using add-ons can slow Firefox down, so if you start installing quite a few you may get performance issues.

Is it worthwhile to load windows 7 onto my MacBook Air? Will it slow down my computer?

Is it worthwhile to load windows 7 onto my MacBook Air? Will it slow down my computer? What might be the benefits of having windows and mavericks as two different operating systems side by side?

Check out this article first. It deals with BootCamp vs Parallels Desktop but there are two other products: VMWare Fusion and VirtualBox that offer the same basic features as Parallels. So your first decision is which you prefer. As I said, I chose virtualization: Parallels Desktop in particular.
You need a full retail version of Windows - If you live in the States try New Egg for the best price. This is what I bought. You'll need it whether you choose BootCamp or virtualization. Note that Win7 apparently isn't available via download from Microsoft any longer, only Win8 so you'll need access to an external optical drive or use remote dvd sharing with your Windows computer. I've not tried installing Windows using remote DVD sharing but I have installed other software that way so I'd expect it to work if you choose virtualization. If you choose BootCamp you'll need access to an external optical drive or create an ISO image of Windows on a large flash disk.

Boot drive in Bay 3 or Bay 4 will it slow down the startup process?

If I have my boot drive in Bay 3 or Bay 4 will it slow down the startup process? I know in old PCs it would look for the boot drive by looking each time in a certain order. If the MP did that then it would probably look at Bay 3 and Bay 4 last on its ordered sequence.

But.... I think there is a but here... Mac OS does still look for other boot drives none the less.
On a PC, most have an option in the BIOS to set the device types (CDROM, hard drive, USB). and the order of hard drives to look. Meaning that I can have a system on a hard drive that is off line, pop it in, make it the primary boot device and boot from it, and boot quickly.
Sometimes people will disable a chipset or not enable hardware RAID on the motherboard.
Startup Disk control panel sets the boot path in nvram and even if you do have 4 boot drives in Mac Pro, it should still boot in 20-45 seconds.

If my SSD on my Air is almost full, will it slow down the computer?

If my SSD on my Air is almost full, will it slow down the computer? As in, if I have about 20GB left on my SSD, will the computer run slower?

Rule of thumb tends to be that you should set aside 10% of disk space for SSDs for the best speed. This comes from SSDs in Windows PCs, where the SSDs do perform more slowly when full rather than having some free space. This is just how SSDs work, which I won't get into the technicalities of. The SSD controllers themselves allocate set a reserve space (this could not be true in Apple's case, depending on what chips they use), but generally the more free space the better. So 64GB should set aside 6GB, 128GB should set aside 12GB, and 256GB should set aside 25-26GB.
SSDs technically will never be as fast as when you first got it. They slow down as soon as you start to write data to them, but the slowdown will be negligible. It's still faster than a HDD at the end of the day.

Yosemite upgrade slowing down my Macbook

Hi - I recently upgraded to Yosemite OS X and it has slowed down my Macbook (2011 model, 2Gb RAM). Everything runs painfully slow - booting up, opening any applications, opening Chrome, Thunderbird - EVERYTHING. Its been suggested I add RAM but not being a techie Mac user i havent a clue how to do that and not really sure i want to throw more RAM at an old-ish machine. I read on the forum about EtreCheck and am hoping this report may help me get some answers?
Thanks

Safari and iTunes will not open on my Macbook Air after Migration Assistant

I did the Migration Assistant via wireless (from Macbook Pro TO Macbook Air) last night and it did work. However, my Safari and iTunes will not open on my Macbook Air now. The error messages are as follows:
Safari: "Safari quit unexpectedly. Click Reopen to open the application again. Click Report to see more detailed information and send a report to Apple."
- I tried reopening the app, restarting, and shutting down the computer. Nothing has worked.
iTunes: "The file 'iTunes Library.itl' cannot be read because it was created by a newer version of iTunes. Would you like to download iTunes now?"
- I clicked "Download iTunes" but then another message comes up that all my software is up to date.
Any help is very appreciated.

Should i shut down my macbook air each night

how often should i shut down my macbook air?

if youre not using it for a few hours
leaving your macbook both ON charge AND in sleep mode is bad on the battery
merely in sleep is another matter, which is fine.
Considerations for the long life of your MacBook. Handling and environmental care tips
General consideration of your MacBook battery
Contrary to popular myths about notebook batteries, there is protection circuitry in your Macbook and therefore you cannot ‘overcharge’ your notebook when plugged in and already fully charged.
However if you do not plan on using your notebook for several hours, turn it off (plugged in or otherwise), since you do not want your Macbook ‘both always plugged in and in sleep mode’.
A lot of battery experts call the use of Lithium-Ion cells the "80% Rule", meaning use 80% of the full charge or so, then recharge them for longer overall life. The only quantified damage done in the use of Lithium Ion batteries are instances where the internal notebook battery is “often drained very low”, this is bad general use of your notebook battery.
A person who has, for example, 300 charge cycles on their battery and is recharging at say 40% remaining of a 100% charge has a better battery condition state than, say, another person who has 300 charge cycles on their battery and is recharging at say 10-15% remaining on a 100% charge. DoD (depth of discharge) is much more important on the wear and tear on your Macbook’s battery than the count of charge cycles. There is no set “mile” or wear from a charge cycle in specific. Frequent high depth of discharge rates (draining the battery very low) on a Lithium battery will hasten the lowering of maximum battery capacity.
All batteries in any device are a consumable meant to be replaced eventually after much time, even under perfect use conditions.
If the massive amount of data that exists on lithium batteries were to be condensed into a simplex, helpful, and memorable bit of information it would be:
1. While realistically a bit impractical during normal everyday use, a lithium battery's longevity and its chemistry's health is most happy swinging back and forth between 20% and 85% charge roughly.
2. Do not purposefully drain your battery very low (10% and less), and do not keep them charged often or always high (100%).
3. Lithium batteries do not like the following:
A: Deep discharges, as meaning roughly 10% or less on a frequent basis.
B: Rapid discharges as referring to energy intensive gaming on battery on a frequent basis (in which case while gaming, if possible, do same on power rather than battery). This is a minor consideration.
C: Constant inflation, as meaning always or most often on charge, and certainly not both in sleep mode and on charge always or often.
