Anyone can confirm that Lion runs as smooth as Snow Leopard with 2GB RAM?

Hello,
I want to install Lion on my 1st gen Air, with 2GB RAM. With Snow Leo, sometimes i have to quit Safari because of the RAM is running low.
So i don't want to upgrade if Lion eats more RAM than Snow Leo.
Can anyone confirm that is it worth to install Lion on a laptop with 2GB RAM?
Thanks

I have a late 2007 2.0GHz Macbook with 4GB of RAM. Snow Leopard ran beautifully on it ( I am a web developer and video editor ).
I clean installed Lion last week and it is very sluggish. It'll often hang and 'spinning beach ball' when doing the simplest tasks such as trying to scroll through a web page, switch applications, open a print dialogue box, etc.
The new UI, animations, and some of the new features of Lion are nice, but I'm considering switching back to Snow Leopard. As a power user on an "older" machine, Lion just doesn't cut it. Depending on what you use your laptop, you might have a fantastic experience with Lion. It certainly takes more video memory, so it's likely newer machines won't struggle with it at all. my concern is that the simple elements of the OS have problems running on my machine, meaning one of two things: 1) Lion is built to run well on newer machines with newer hardware or 2) Lion is built poorly. It seems more likely the former is true. in either case, if you have a "base" machine like Macbook or Mac Mini 2008 or older i'd say stick with SL. otherwise upgrade to your heart's content.

How can I unistall Lion and go back to Snow Leopard?

I upgraded to Lion (stupidly and blindly) and now most of my programs are not compatible. What is the process to go back to Snow Leopard?

Given the lack of response to this particular discussion, and given all the various and sundry ideas on this topic, I have had a panic-stricken 48 or so hours since I asked my question. Here's what finally worked to get me back to normal:
1. First, I gritted my teeth and erased my hard drive, hoping and praying I'd be able to restore from Time Machine. I'd been backing up for quite some time, but never needed it before. HOWEVER:
Lion evidently left little gremlins all over my hard drive, because I simply could not get my hard drive restored properly, not from the Time Machine restore function on the SL disk NOR from a manual "Star Wars" pick and choose with my Time Machine. Therefore (and this is important):
I zeroed out my hard drive completely, after trying for an entire day to get things back to normal. What you have to do is start up from the Snow Leopard disk, and do a COMPLETE erase, by which I mean that when you use DU to erase your hard drive, you go into the "security" panel on th DU screen and do a 7-pass zero-initialization of your hard drive, i.e., write zeros all over everything on your hard drive seven times, leaving it truly free of that yucky Lion. THEN I reinstalled Snow Leopard, ran Software Update several times until it had updated everything it wanted to ad nauseum, and THEN was able to get Time Machine to work properly and bit by bit restored everything I wanted to restore. I am appalled at the lack of accurate documentation that comes with Time Machine, frankly. Anyway, when you get ready to restore your software AFTER you put the Snow Leopard system back on your hard drive and update it, you have to go back to a backup from BEFORE you installed Lion, though: this is important. Don't try to put anything associated with Lion back on your hard drive. For me, that backup was done was last Friday. It took ages, but....my hard drive is now purring like a kitten, and I have Snow Leopard and all my old software back. It was a mess, but it seems to be over. I learned from this disaster how important it is to completely wipe your hard drive clean before trying to reinstall an older operating system. As far as Lion goes, I will be extremely careful before I assume any new upgrade is a good upgrade. It isn't. I LIKE my elderly Adobe programs and my kid likes her games that need Rosetta, as does Word 2004. My Mac is much happier with Snow Leopard. For now. If it ain't broke, don't fix it.

CAN I REMOVE LION AND GO BACK TO SNOW LEOPARD

can i remove lion and return to snow leopard

I see the help offered. I have just posted the same question and now see others with the same problem. Lion may be fine, but for me It's giving me a headache. A couple years ago I switched from a long time PC user to Mac largely because I was tired of the constant "upgrade" "patch and fix" merry-go-round we get with "those other guys". My Macbook Pro worked well with Snow Leopard but was eventually talked into the Lion upgrade. 24 hours later, I'm sorry I did. Some of my software that worked for me is not supported by Lion and neither is my Linkstation (where I have my files and backups). I tried installing the disk that came with the system to revert or return to factory condition but it too returned an error message "...software not supported...". I tried both pressing "C" during startup and when that failed, tried installing from the disk after Lion loaded, same result.
I see that suggested as a solution so I'll try again, just in case I missed something, but if there are other thoughts or suggestions, they are appreciated. I've tried to go into disk utility to partician, nope not allowed, can should I "erase" the current partician or ????
I don't know... thanks for any suggestions to clean this up.
Thanks.

Can't use iPhoto Album as Screensaver in Snow Leopard with iLife '11?

I just upgraded my iMac to Snow Leopard (10.6.3) so I could install iLife '11.
After installing both, I noticed my screen saver wasn't using the iPhoto album I had originally selected before the upgrade.
When going to System Preferences > Destop & Screen Saver > Screen Saver the options are:
Apple
     Arabesque
     Computer Name
     Flurry
     iTunes Artwork
     RSS Visualizer
     Shell
     Spectrum
     Word of the Day
Pictures
     Shuffle
     Abstract
     Beach
     Cosmos
     Forest
     Nature Patterns
     Paper Shadow
There used to be an option for iPhoto albums, or am I just not seeing something?
Thanks,

OS X Lion installed, want OS X Snow Leopard on External HD

I upgraded to OS X Lion (which I love), but I would like to install OS X Snow Leopard on an external hard drive. Unfortunately after inserting the Snow Leopard disk, I am receiving the message: "You cannot install this OS with the current OS you are running"
Would restarting the comp to boot from the Snow Leopard disk work?
If anyone can help, that would be great!

Install Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select the external hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. When formatting is complete quit DU and return to the installer. Install Snow Leopard. Be sure you select the external drive as the installation target.

Battery discharge: Lion 10.7.2 vs Snow Leopard 10.6.8

Has anyone noticed that Lion consumes more resources than Snow Leopard thus causing faster battery discharge?
YMMV, but it would be interesting to see of others can get similar results. Do you suppose Lion 7.3 will increase or decrease resource usage and what affect will it have on battery life?
I called Apple about the battery discharge issue on my 2 week old MacBook Pro with Lion 7.2. I was only getting about 1/2 of the 7.7 WIFI hours advertised. They gave me the usual "if depends" on WIFI, system settings, applications, etc., i.e. such things as cpu and memory load (paging/swapping=>disk i/o), other disk activity, and a few other things.
My large expenditure on the new MacBook spurred me to investigate what was going on using the Activity monitor. I configured my old MacBook Pro (mid 2009) and my new MacBook Pro (late 2011) with the same system preferences. I reset both the PRAM and SMC on both machines to maximize the battery charge (documented elsewhere).
Obviously, a direct hardware comparison would not be meaningful but when you look at the operating systems there is a significant difference between Snow Leopard OS X 10.6.8 and Lion OS X 10.7.2. Lion uses much more resources than Snow Leopard.
My Observations:
The first value I list is for OS X 10.6.8 and the second for OS X 10.7.2. I tried numerous other combinations but these nicely summarizes my results.
1) I started with only the Activity monitor, iTunes Helper, and Epson EEventmanager manager running, No WIFI or any other user processes
CPU % idle               : 98.75 vs 99.4 (i.e. both machines were literally idle)
No. of threads           : 179   vs 277 --> + 55%
Kernel threads           : 60    vs 82   --> +37%
Processes                : 41    vs 54   --> +32%
Wired Memory MB          : 480   vs 864 --> +80%
Active Memory MB         : 198   vs 407 --> +106%
Memory Used GB          : 0.808 vs 1.32 --> +63%
Percentage of 4 GB       : 20%   vs 33% --> +65%
Virtual Machine size GB : 96    vs 149 --> +55%
2) With WIFI and Safari added
CPU % usage              : 72.9 vs 91.02 (i.e. both machines were not very busy)
No. of threads           : 253 vs 376 --> +49%
Kernel threads           : 60   vs 82 --> +37%
Processes                : 51   vs 63 --> +24%
Wired Memory MB          : 669 vs 1007 --> +51%
Active Memory MB         : 600 vs 1190 --> +98%
Memory Used GB          : 1.57 vs 2.47 --> +57%
Percentage of 4 GB       : 39% vs 62% --> +59%
Virtual Machine size GB : 131 vs 191 --> +46%
Look especially at the percentage of memory used. In either case, I measured no paging nor swapping. But, as you can see, with the increase of memory used with Lion when WIFI and Safari were added you could quickly push the memory as more process are added and start paging and swapping to/from disk hence use more battery charge.
The increase in number of threads, processes, memory usage, virtual machine size, and WIFI activity would imply that Lion would have to consume more battery charge than Snow Leopard as you use more cpu/memory to chase more threads.
I looked at WIFI usage and it involves a lot of chatter between the computer and the internet. Over time a lot of packets are sent/received even when no data is being passed and would be a drain on the battery. There would be a greater drain when there is data passed because of the additional CPU and memory needed. But, in todays world, you cannot run without an ethernet or WIFI connection because of the dependency on the information/data on internet cloud.

How do I disable Lion and go back to snow leopard

I up graded to Lion. Now my wireless router can't connect because it doesn't support Lion. I don't want to have to buy a new router.
Can I disable lion and go back to snow leopard?
P.S. I am new at computers so be easy on the terminology please.

It would help if you gave some information on WHY the router isn't working. Start with the basics:
-What brand and model is the router? If you can get a version number, that is also sometimes helpful. This info is generally printed somewhere on the router, usually a label on the back or bottom.
-What do you mean by "doesn't support" - did you get this info from the manufacturer, or is this based on you not being able to connect? Routers use standard wireless protocols (called 802.11a/b, g, or n). The network cards in Mac computers also use these same protocols.I can't think of a reason why it shouldn't work.
-Does your router have a wired connection? If so, can you connect with an Ethernet cable? You may need to be able to connect to the router directly to change settings.
-How old is your router? And have you ever tried to upgrade the firmware settings on it?
-Can you connect to ANY wireless routers anywhere else with your Lion computer?
-Do you have any OTHER computers (Windows or Mac) that can successfully connect to your wireless router?

I recently updated? to Lion from 10.6.8(snow leopard), and things seem to be running slower. Has anyone had similar problems? I have Feb 2011 Macbook pro 13" 2.3 Ghz.

As Shootist pointed out, the system uses more power.
However, initially it will reindex the hard drive for spotlight, which will slow things down temporarily.
It also must rebuild caches that eventually will speed things up.
If it has completed indexing the hard drive (no dot pulsing in the spyglass), then there might be something wrong.
Start by booting into the Recovery HD (a partition created with Lion that has Disk Utility and reinstallation options) by holding down cmd-r when you restart. You can let go when the gray screen appears.
When it boots, select Disk Utility and Repair the drive.
If that doesn't speed things up, try re-installing the OS from the same Recovery HD. It won't delete any of your files, but it has helped some people whose Macs ran slow after installing Lion.
Also, how much memory do you have? Lion needs RAM so maxing your Mac out might also help.

Can OS X Lion Run Windows 7 x64 Bit?

Hi Guys,
"Can OS X Lion Run Windows 7 x64 Bit?"
- I can see nothing in the bootcamp section that states it must be x32 bit?
... Soooo Yea...
- Dave.

Apple told me to NOT download the Boot Camp driver for Windows using the Boot Camp Assistant application in Mac OS X 10.7 Lion. I was told to download Boot Camp Software Update 3.1 for Windows 64-bit from the Apple website or use the ones that were included on the Mac OS X 10.6 disc providing they were at least version 3.1 and install those. Then I was told to run Apple Software Update to see if there were new Boot Camp drivers available and if there were to download and install them and to then run Apple Software Update to see if there was another version after that and if the was to install that one if not then I had the latest version. I take it that the latest version is 3.2 which was released 18 November 2010 since it didn't tell me about a newer version.

S10 owner, can confirm that power adapter in your package is Lenovo brand or oem brand?

Hi all,
I just bought new Lenovo S10 (or S10e, the screen is glossy type). My package come with oem power adapter.
Anyone can confirm, I should get lenovo power adapter or since begining, lenovo only provide oem power adapter for all S10?
I very disappointed when I call Lenovo technical support hotline, they said, lenovo or oem brand same, similiar, same function, etc.
Then why they have lenovo.com ? lenovo word mean nothing right ?

Hi Plusnplus,
My S10e (4187-5LG, January 2009) came with a Li Shin power adapter ... And a WD hard drive, a Sanyo battery + internal components from lots of other manufacturers! The Lenovo warranty on the whole package (except the battery) is 2-4 times better than the minimum requirements in Denmark. That is what makes the difference for me.
By the way: The power adapter for my IBM L40SX (~1991) portable computer is "made in Japan" OEM with an IBM sticker on it.

When dragging an image onto a fresh canvas, the resizing feature presnaps the image into the canvas size. I can confirm that this has not happened to me in previous projects. I've also tested this problem by making a new larger document size and dragging in the same render. It snaps again. I don't want to re-size from the canvas dimensions, I want to resize from the render's original dimensions.

I am currently running Leopard (10.5.8) on my late 2008 iMAC. I want to upgrade to Mountain Lion and I have been informed that I must first upgrade to Snow Leopard first. What operating issues could I face after doing this?

Based on user issues I am reading should I even attempt this. One of my reasons of wanting to upgrade is to have the ability to upgrade to newer versions of certain programs such as Lightroom and Adobe Photoshop.

I've upgraded several Mac from 10.5 to 10.6 and all the installations were trouble-free. However, in an abundance of caution, back up before you start upgrading.
RAM: Most 2008 iMac shipped with 2GB RAM. Your iMac 2008 can use up to 4GB RAM "officially" and up to 6GB with memory modules introduced since Apple's offical specs were engraved in stone. Although 10.6 may do ±OK with 2GB, I suspect Photoshop is glomming on to all you have. Lion10.7 will just barely work with 2GB and 10.8 Mtn Lion may slow to a crawl.
I get all my RAM upgrades here:

Never had a problem with any of their RAM and I've been getting it from them for over a decade--and we have 18 Macs in the family!

Can't run PowerPC apps under Snow Leopard. Why?

I just upgraded to Mountain Lion on my main hard drive. I also installed Snow Leopard on an external drive to run some older PowerPC apps I have that Lion and Mountain Lion don't support. Snow Leopard is supposed to run PowerPC applications just fine. So I installed those apps on the same drive as SL, but when I start up from that drive, the apps won't open? The system starts up just fine from the external drive, but when I try to open the apps, they just bounce in the dock at the bottom of the screen for a few seconds (like they're starting up). Then they go away and don't start up. No error warnings, no crashes. Nothing. I've restarted after the installs, checked to make sure folders weren't locked, etc. I can think of no reason why the apps won't run under SL on an external drive. Anyone have a guess?

Obviously you are unaware of the advice I give on this forum: You're preaching to the choir!

Can I move Mail (Lion) files back to Mail (Snow Leopard)?

Hi,
I've encountered a screwy problem and am wondering if there is an easy fix. I have an iMac at the office that is now running Lion, and a MacBook Pro at home running Snow Leopard (which I am keeping there for now because of the Quicken issue with Lion). Anyway, my laptop hard drive totally failed (still trying to recover the data but have been unsuccessful so far...worst drive failure I've ever encountered...even TechTool Pro tech support couldn't help) and I lost literally 10s of thousands of emails over the last many years. I have the vast majority of those emails on my iMac, but the file structure is all changed now so it is not straightforward to just copy-paste folders from the iMac (Lion) to the MacBook (Snow Leopard).
I can think of two tedious ways to move the files:
1) Actually burrow into the ridiculous level of folders in the Lion Mail structure and copy directly...but I'm not willing to spend that time for 10s of thousands of emails.
2) All prior years emails are in folders "On My Mac" on the iMac, so I can re-upload the emails via IMAP and then download them to MacBook...but this is tiresome.
That said, is there a way to easily backward import the Lion Mail files to Snow Leopard Mail?
Thanks,
- DC

Hi everyone,
I was able to import my Apple Mail after downgrading from Lion to Snow Leopard.
Here is what I did:
- In Mail, click Mailbox > New Mailbox.
- in the New Mailbox dialog box, select "On My Mac" as the location and give it any "MailboxName" you want. Click OK.
- Now in Finder, open Library > Mail > Mailboxes > MailboxName.mbox. In the MailboxName.mbox folder (where MailboxName is whatever name you gave the mailbox), all you'll see is an info.plist file. Add a folder called "Messages".
- Go to the location where you've backed up all of your email from Lion and drill down to the Messages folder where you have all your .emlx files. Copy all of these .emlx files and paste them into the new Messages folder you've created (i.e., at the Library > Mail > Mailboxes > MailboxName.mbox > Messages location).
- Go back to Mail. If you open the new "MailboxName" folder under "ON MY MAC", you'll see that it is still empty. Snow Leopard Mail can't read the .emlx files from Lion Mail. But we're not done yet. There are some more steps.
- On the Mail File menu, click Import Mailboxes.
- Select Apple Mail and click Continue.
- Browse to Library > Mail > Mailboxes, select "MailboxName.mbox", click Choose, and then click Done.
- Snow Leopard Mail will now import Lion Mail. It creates an "Import" folder in Mail under "ON MY MAC". Expand the Import folder and you'll see a a folder with the "MailboxName" you selected. When you open this you'll see all of your mail items that came from Lion Mail.
- You can repeat the above for each mailbox you want to import.

Anyone can confirm that Lion runs as smooth as Snow Leopard with 2GB RAM?
