File sizes have grown in Snow Leopard

I switch between Leopard and Snow Leopard on my Mac.
I have set up folders to backup to DVDs and was amazed to find that the files change size (get bigger) in SL.
eg. Leopard 6 files are:
+700.1, 700.4, 701.9, 841.2 & 828.4 Mb for a total of 4.37 Gb+
The same 6 files in Snow Leopard on the same Hard Drive:
+736.1, 734.1, 734.5, 736, 882.1 & 868.6 Mb for a total of 4.69 Gb+
Which does not fit on a DVD.
Anyone know what is going on here?
Peter

So it just comes down to an (in)accurate definition of a Mb?
It's not inaccurate. Apple is now using the same definition of MB that is recommended by the International Standard of Units and the International Electrotechnical Commission. Most (all?) hard drives are labeled with this unit rather than the base-2 megabyte. This causes confusion to consumers who think the OS is short-changing them when a drive that's supposed to be 500 GB is actually quite a bit less. That confusion is gone in SL. Note that Ubuntu will be moving to the same base-10 units in the next version. I wouldn't be surprised if the old base-2 units are a thing of the past in 5 years.
That still doesn't help though when I need to burn to DVD with Toast.
As with all such changes, there's a period of growing pains. Until Toast is updated for the newer units, simply convert the maximum capacity of a DVD from base-2 to base-10 and then keep that capacity in mind when building your list of files for the DVD.

I am new to mac's and have upgrade from Snow Leopard to Lion but......

I am new to mac's and have upgrade from Snow Leopard to Lion but not all my application will work. Is it save to reinstall using original snow leopard dvd and does it wipe all my other application like apature? I am in a panic over this, any help!!
I came across this online and i want to know is it safe to do this:
Backup your User folders to an external drive. This should preserve your documents, photos, music, etc. If you store those things in locations not in the User folder, make sure to copy those over too.
Insert the Snow Leopard disc. Restart your Mac and hold down C to boot to your DVD drive.
Go to Utilities in the menu bar once the installer pops up and select “Disk Utility.”
Find the drive in the sidebar where Lion is installed, select it and navigate to the Partition tab.
Click on the drop down menu under Partition Layout and select “1 Partition.” Hit Apply.
Now navigate to the Erase tab and make sure “Mac OS Extended (Journaled)” is selected, then hit Erase to delete all data on the drive.
Quit Disk Utility to get back to the Snow Leopard installer and proceed with the install.
Restore your User folder and documents from your backup.
Run Software Update to get everything current, install your apps from your original install media and update those as well.
if any one can help me that would be great, thanks Mike

Before you do that why not do this first:
Repair the Hard Drive and Permissions
Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
To boot from the Recovery HD restart the computer. After the chime hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
If this doesn't help, then you can proceed to reinstall Snow Leopard as follows:
Downgrade Lion to 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 your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, 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 then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard. I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
This will erase the drive so be sure to backup your files before doing this.

I have updated from Snow Leopard to Lion with Safari Version 5.0.5. Now I can not update to Safari 5.1. There is no update in the Software Updater, and on the apple-download page, I only found a Safari 5.1 for Snow Leopard. When executing it, there is an error message, that it is for 10.6 only.
It seems that I should have first updated Safari, and then only to Lion, which I didn't. Any idea how I can fix this now without having to rollback to Snow Leopard, update Safari and then go back to Lion?

Try this Safari5.1 from the installer package

The download worked better with Firefox not sure why. At the bottom of the page after the captcha>> slow down load is the Free link, it took about 4 minutes to download on my test.

Renaming a file in Finder changed with Snow Leopard somehow?

I've used an AppleScript for ages to:
1. choose a file (a screenshot)
2. prompt for a new name
3. File is renamed by Finder with new name
4. compose a command to copy it to another server
It seems Finder is not updating the "alias" to the file since I upgraded to Snow Leopard; this very code has worked for the last few versions of OS X:
set screencap to (choose file with prompt "Choose the screen shot: ")
display dialog "Enter new file name: " default answer "foo"
set newname to (the text returned of result as string)
set newnamepng to (newname as string) & ".png"
log "newname is " & newname & " newnamepng is " & newnamepng
log "screencap is " & screencap
tell application "Finder"
set the name of screencap to (newnamepng as string)
end tell
log "the name of screencap is now: " & screencap
set posixscreencap to the POSIX path of screencap
set scpcmd to "scp " & posixscreencap
log scpcmd
Here's what happens when I run it:
tell application "AppleScript Editor"
choose file with prompt "Choose the screen shot: "
--> alias "Einny:Users:swain:Desktop:Screen shot 2010-09-13 at 2.06.44 PM.png"
display dialog "Enter new file name: " default answer "foo"
--> {text returned:"newnameforscreenshot", button returned:"OK"}
end tell
(*newname is newnameforscreenshot newnamepng is newnameforscreenshot.png*)
(*screencap is Einny:Users:swain:Desktop:Screen shot 2010-09-13 at 2.06.44 PM.png*)
tell application "Finder"
set name of alias "Einny:Users:swain:Desktop:Screen shot 2010-09-13 at 2.06.44 PM.png" to "newnameforscreenshot.png"
--> "newnameforscreenshot.png"
end tell
(*the name of screencap is now: Einny:Users:swain:Desktop:Screen shot 2010-09-13 at 2.06.44 PM.png*)
(*scp /Users/swain/Desktop/Screen shot 2010-09-13 at 2.06.44 PM.png*)
For some reason the file alias "screencap" does not get a new name. Any suggestions?

When I run your script, the file name does get changed, it is just that the Finder is not keeping up with the script. There are a few fixes:
1) add a short delay after the rename (delay 1 seems to be enough)
2) use *System Events* instead of the Finder
3) add an update command after setting the name in your FInder tell statement (e.g. update screencap)
Note that an alias will still point to the same file item (even if it does have a different name), but the POSIX path of the alias object does need to be updated before you can use that.

File sharing requires Internet in Snow Leopard?

I have two Snow Leopard Macs (10.6.5) and One Tiger (10.4.11) Mac all connected by cable to a router, each with a static IP address. When I have the Internet connection plugged into the WAN port of my router and modem turned on, file sharing works fine from any Mac to any other.
But if I have the Internet turned off and start up the computers, I cannot connect to a Snow Leopard machine to access the hard drive from either a Tiger machine or the other Snow Leopard machine. When I choose connect to Server in finder, and put in the IP address of a Snow Leopard Mac, it just times out, like that Mac don't exist on the network. I remain able to connect to the Tiger machine to access its hard drive via file sharing.
Why does Snow Leopard seem to need an Internet connection in order to be reached for file sharing on the LAN?
Thanks in advance.

I finally got to the bottom of the file sharing issue. I had the Snow leopard machines' network preference setting "Configure IPv4" set to "Manually". I had entered the IP address, router, subnet, and DNS server for each machine. DNS server was set to be the router, as I have my preferred DNS servers configured in the router. If I change Configure IPv4 to "Using DHCP with Manual Address" and remove the DNS server from Network preferences, causing it to be obtained from the router, this fixed the issue. (The DNS server still shows as the router's address, but it is now supplied by DHCP.)
I am still curious why configuring both the IP address and DNS manually causes the issue, while using DHCP for the DNS with fixed IP address fixes it.

I have 10.5.8 and want to upgrade, Do I have to download Snow Leopard before download the Mountain Lion?

I have 10.5.8 and want to upgrade, Do I have to download Snow Leopard before download the Mountain Lion?

Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You must purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s MobileMe service; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion - System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
         7. Xserve (Early 2009) - Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
     Are my applications compatible?

Mail has gone crazy. Header's and messages are mixed up. New Mac Book Pro. Migrated files from Time machine running snow leopard. Reinstall or new computer needed?

Ok; I'm not sure what you're doing. 36 hours is rather long. Seems like a new migration. Not what I intended.
Here's what I intended: from the newly-migrated and apparently-corrupt environment, create a new user, not related to any existing user, nor any migration-created user, or any other user for that matter. That is, use  > System Preferences > Users and Groups, authenticate yourself by clicking on the padlock, and then click the + and create a wholly new user. Then log in under that user and establish the mail access.
36 hours? I'm wondering if there's an error or an exceedingly slow network here? Or a really, really slow disk? Or a sick backup? (WiFi isn't the path I'd usually choose, either.)
Failing the attempted second migration, I'd try a different tactic. Does your existing (old) system work? If so, I'd bypass the backup and connect an external (scratch) USB disk drive to the (old) sstem and then boot and use Disk Utility booted from the installer DVD disk or boot and use Disk Utility from the recovery partition or booted from a recovery partition created on some other external storage (details here vary by the OS X version and what hardware you have), and perform a full-disk backup of your original internal disk to (scratch) external storage. (Make sure you get the source and target disks chosen correctly here; copying the wrong way — from the scratch disk to your existing disk — will clobber your data!) In esssence, this will clone your existing boot disk. Then dismount the (formerly-scratch) external disk, transfer it over to the new system, and use it as the source of the migration, by performing a fresh OS X installation on the new system.
Target Disk Mode is also sometimes an option for accessing the disk for a migration, but that requires the right cable, and requires systems that have the same external connection; newer MacBook Pro systems use Thunderbolt for this, and older systems tend to use FireWire. And I'm guessing you don't have compatible hardware.
The details here can and do vary by your OS X versions and your particular Mac systems — if you'll identify the specific models and hardware, somebody might be able to better tailor the above (fairly generic) sequence to your particular configuration.

I have a Window 7 HP laptop. I want to install Snow Leopard on an external hard drive as the memory space on my laptop is very less. I have the original snow leopard disc and I think it's a retail version . Please guide me through the installation in details. Can you also please let me know about this boot camp.

You cannot. From a legal standpoint, the license agreement for OS X mandates that you run OS X only on Apple hardware. HP is not (yet) owned by Apple.
From a technical standpoint, your HP laptop doesn't use EFI, but rather an early predecessor called a BIOS. Apple is the only vendor of consumer computer hardware that uses EFI; other vendors reserve EFI for use in servers.
Secondly, Apple's operating systems support a rather limited number of configurations of video hardware and mainboard chipsets directly since they need only support those systems that they manufacture. You cannot use Windows software or drivers on OS X, so prior to installation, you would need to write your own hardware drivers for your laptop, create an OS X drive image on a Mac, and then modify that image with your drivers before putting it in the HP.
It will be simpler (and legal), to simply purchase a used Mac. Apple's online store has refurbished MacBook Airs starting at $850 and Mac Minis for $700. If you go to e-bay or craigslist, you'll find used Macs for considerably less.

I wanted to buy a Dragon ,Speech Recognition Programme for Mac but it says its for Lion, and I have Snow Leopard. Would it have worked on Snow leopard?

I wanted to buy a Dragon ,Speech Recognition Programme for Mac but it says its for OS Lion, and I have OS Snow Leopard. Would it have worked on Snow Leopard?

The simplest method would be to ask them for their Snow Leopard version and say you can't upgrade to 10.7 or 10.8. I'm almost sure they will sell you a copy.
Generally if your machine can only upgrade to 10.7 Lion and not directly to 10.8 Mountain Lion, then it's best left on 10.6.8. in my opinion as your going to loose too much other software and slow down your machine in the process.
This rapid OS X upgrade cycle has caused plenty of problems for users and developers alike, so I suspect you will find a sympathizer with the developer.
In fact I'm not recommending Mac's to anyone anymore because Apple simply has lost touch with reality.

I used Roxio VHS to DVD for Mac (have iMac with Snow Leopard) and the audio does not synch with the video when playing in iMovie. Any suggestions to fix?

Thanks for the reply. I tried playing with detaching the audio in iMovie, but with 20+ hours of video to correct, it would take too long. After 28 hours, Corel/Roxio tech support replied that it is a known bitrate mismatch problem and they have no real fix. I strongly suggest not to buy this product.

Ian, this might help explain it a bit more:
http://osxdaily.com/2011/06/07/mac-os-x-10-7-lion-system-requirements/
It's only available from the store, and you need 10.6.6 to access the store. But if you can download it using 10.6.6 on another machine, you'll be able to install it on a machine meeting the hardware requirements (it doesn't matter which OS was installed on it).
