Spaces in Mac OS X Lion

I'm wondering how Spaces work in Lion.
Currently I use a 3x3x(27"iMac+22"LG monitor) setup and I'm afraid that I won't be able to use a similar setup on Lion, because if I understand the developer videos correctly, then Apple decided to continue with a ONE-dimensional Spaces implementaion, down from the TWO dimensions in Snow Leopard.
So my question is, will I be able to activate 2-dimensional Spaces? I really need this ability for my workflow.
I open TeXShop in the mid Space, so that I can quickly access the 4 adjacent spaces, which contain Safari, Maple (CAS), Numbers and the last one mostly PDFs. Therefore, I rely on the ability to switch to the desired space with one shortcut, and it doesn't improve my workflow if I've to switch to the forth Space and back, when I want to check something on Wikipedia for instance, which would take 6 more actions in the worst case.
Furthermore, will I be able to see all the spaces at one time, and seeing all the spaces, can I, like in Snow Leopard with 4 finger swipe down, see ALL my open windows at once? This is a feature I use a lot and because I can magnify the windows with 'space' it's a real time saver for me.
Please don't get me wrong, from what I've seen about Lion, I like it a lot, but I hope that the new features will coexist with the good and easy to use old ones.
At least I'd like to be able to choose to use the old method in the preferences, if they can't coexist.

Also be aware that things posted on those sites may be from earlier versions, not the one that's going to be released (or made up entirely).
During development, many items are changed or disappear entirely, and new things introduced.
Patience.

Before Mac OS X lion install I had over 50% free hard drive space on new MBP, but now my hard drive is full without me doing anything! How do I fix this??? Or should I just revert to Snow Leopard???

Sounds like the Time Machine Local Backup. Try turning Time Machine Off in System Preferences to verify.
See: OS X Lion: About Time Machine's "local snapshots" on portable Macs
But, your real problem is
I forgot to mention that I tried to use Disk Utility to Verify Disk, but it cannot. I get red errors that say the MacHD is corrupt and needs to be repaired. It says that in order to do this I need to use the Disk Utility on the install disk, but Lion doesn't have one!
Boot into Lion's Recovery (Hold ⌘R on Boot), select Disk Utility and then select Macintosh HD and click [Repair Disk]

Just downloaded mountain lion but it told me not enough space on Mac HD. What do i do?

I just downloaded mountain lion and it told me that I have to pick a disk to put it on. There is not enough space on Mac HD because apparently time machine backs up on there. What do I do? Can I back that up somewhere else?

HOw much avaiable space do you have on that volume?
Do you have a partition for TM, or are these local snapshots (is it a MacBook or MacBook pro)?
Either way you'll need to free up space by moving data off the drive.

SQLDeveloper 3.1 on Mac OS X Lion

Hi guys,
sorry for reposting, but this is really pressing -- doesn't anyone use SQLDeveloper on Mac OS X Lion?
I have a pretty recent Mac OS X System (10.7.3, today updated from 10.7.2 -- the problem existed there as well) with Java 1.6.0_29:
localhost:~ bgd$ /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java -version
java version "1.6.0_29"
Java(TM) SE Runtime Environment (build 1.6.0_29-b11-402-11D50b)
Java HotSpot(TM) 64-Bit Server VM (build 20.4-b02-402, mixed mode)
I installed SQLDeveloper 3.1.0.7.42 on this system and I've encountered the following two problems:
1. the connections aren't saved. Everytime I delete the ".sqldeveloper" directory in my homedir, SQLDeveloper starts without any problems. I can add a connection, test it, connect to the database and even saving it doesn't show any errors. A "connections.xml" file is generated but empty:
localhost:~ bgd$ find .sqldeveloper/ -name connections.xml -ls
1733256 0 -rw-r--r-- 1 bgd bgd 0 Feb 9 17:43 .sqldeveloper//system3.1.07.42/o.jdeveloper.db.connection.11.1.1.4.37.59.48/connections.xml
If I start the SQLDeveloper w/o deleting the "~/.sqldeveloper" directory I always get the following errors:
oracle.jdeveloper.db.DatabaseConnections DatabaseConnections has no JNDI context so cannot list connections.
oracle.jdevimpl.db.adapter.DefaultContextWrapper Failed to create naming Context for db connections at url: file:/Users/bgd/.sqldeveloper/system3.1.07.42/o.jdeveloper.db.connection.11.1.1.4.37.59.48/connections.xml
oracle.jdevimpl.db.adapter.DefaultContextWrapper Failed to create naming Context for db connections at url: file:/Users/bgd/.sqldeveloper/system3.1.07.42/o.jdeveloper.db.connection.11.1.1.4.37.59.48/connections.xml
The connections.xml file remains empty, no matter how may connections I add and "save".
2. After I make a connection to a database, I try the "SQL Worksheet" option (either by right-clicking the DB Connection or thru the menu "Tools->SQL Worksheet"). But nothing happens (except for the dialog "Select connection" when calling thru the "Tools" menu) -- no new window, no "SQL Workshop" space on the right canvas, nothing.
I've googled the first problem (the second one is pretty hard to "formulate") and, based on the results, I also tried the following:
- Set the right Java Home in sqldeveloper.conf and sqldeveloper-Darwin.com:
SetJavaHome /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
- tried to add the following lines to sqldeveloper.conf and sqldeveloper-Darwin.conf:
AddJavaLibFile ../../lib/java/api/jaxb-api.jar
AddJavaLibFile ../../lib/java/api/jsr173_api.jar
AddJavaLibFile ../../j2ee/home/lib/activation.jar

AddJavaLibFile ../../lib/java/shared/sun.jaxb/2.0/jaxb-impl.jar
AddJavaLibFile ../../lib/java/shared/sun.jaxb/2.0/jaxb1-impl.jar
- I checked, but there is no ORACLE_HOME variable set on my system
- Right now the java process looks like:
bgd 1411 0.0 3.9 3831552 326400 ??

Any hints what could be wrong? I'm running out of ideas here...

Hello John, hello Brian,
thanks for the fast answer!
So, I've "cleaned up" the conf files. Now they look like this:

java.ext.dirs /Users/bgd/Library/Java/Extensions:/Library/Java/Extensions:/System/Library/Java/Extensions:/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/lib/ext
It is a new Mac OS X Lion installation, but I've restored my home directory from a previous Mac OS X installation -- it is possible that some "old" files from the old installation (where I've also used SQL Developer, but deleted it) are interfering with the new one.
Greetings,

HT3986 i made a dual boot of windows 7 and mac os x lion in my macbook pro .i installed microsoft support software also. now, can i install windows updates? do i turn on the automatic updating of updates?

i made a dual boot of windows 7 and mac os x lion in my macbook pro .i installed m icrosoft support software also. now, can i install windows updates? do i turn on the automatic updating of updates?

yes you need the updates and patches.
Only some of the drivers that Windows will automatically install at times
and always make sure to insure it is using restore points
do all the maintenance andsuch as normal
use MS Security Essentials for AV is really top notch
Clean disk space
Use WinClone new program to inisure you have a restore image

Is MAC OS X v10.6.8 same as MAC OS X Snow Leopard. Since i want to download MAC OS X LION can it be downloaded on my mac which has MAC OS X v10.6.8 ??

Yes, assuming you can run Lion, & can deal with no more Save or Save As... functions...
Lion/101.7 System requirements
    •    x86-64 processor (Macs with an Intel Core 2 Duo, Intel Core i3, Intel Core i5, Intel Core i7, or Xeon processor.)
    •    At least 2GB of memory, (I say 4GB)
    •    Latest version of Mac OS X Snow Leopard (10.6.8), with the Mac App Store installed
    •    At least 4GB of disk space for downloading, (I say 40GB at least)
Like Snow Leopard, Lion does not support PowerPC-based Macs (e.g., Power Macs, PowerBooks, iBooks, iMacs (G3-G5), eMacs).
Lion also does not support 32-bit Intel Core Duo or Core Solo based Macs. Rosetta is no longer available in Lion, which means Lion no longer supports PowerPC applications.

Mac OS X Lion shows excessive disk storage usage for movies ... about 3 times the expected size.

I have about 65GB of movies on my Mac OS X Lion. However, when I look up my storage usage from "About this Mac -> More Info -> Storage, it shows 208 GB. I tried querying up all Movie files, and it comes back with only 65-70GB. Any ideas where the extra storage is being reported from?
Thanks

Then you actually do have 208 GB of movies.
To locate large files, you can use Spotlight as described here. That method may not find large folders that contain a lot of small files.
You can also use a tool such as OmniDiskSweeper (ODS) to explore your volume and find out what's taking up the space. You can delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one.
Proceed further only if the problem hasn't been solved.
ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
Install ODS in the Applications folder as usual.
Triple-click the line of text below to select it, then copy the selected text to the Clipboard (command-C):sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste (command-V) into the Terminal window. You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
I don't recommend that you make a habit of doing this. Don't delete anything while running ODS as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means.
When you're done with ODS, quit it and also quit Terminal.

Mac OS X Lion 10.7.3 is slow. What can I do?

Mac OS X Lion 10.7.3 is slow. What can I do?

Welcome to Apple Support Communities.
You don't mention what model you have or how old it is.
The normal recommendation would be to add more RAM (2GB minimum, and 4GB or more helps Lion run faster), but since you have a MacBook Air, that's just not possible because MacBook Air RAM memory cannot be upgraded.
If you are very short of hard disk space, you could get a larger hard disk, but the only options are SSD's (Solid State Disks). A larger SSD might not increase performance substantially. A reliable vendor such as Other World Computing (http://eshop.macsales.com/search/MacBook+Air+disk) does have lots of SSD options though.
If your MacBook Air shipped with a version of OS X prior to 10.7 Lion, (Snow Leopard 10.6, or Leopard 10.5), you could potentially reinstall that version. Here are some related links:
https://discussions.apple.com/thread/3303773?start=0&tstart=0
http://www.pcmag.com/article2/0,2817,2389334,00.asp
Another option is to sell your current model and purchase one that offers better OS X Lion performance. (More RAM, faster clock speed, i5 or i7 processor).

HT1338 Software Update is not finding latest release (April 3) of Java 2012 001 Update for Mac OS X Lion 10.7.3 on iMac mid-2007 that downloaded automatically on iMac mid-2011

Software Update is not finding latest release (April 3) of Java 2012 001 Update on my iMac mid-2007, but it downloaded it automatically on my iMac mid-2011 yesterday. Both are running Mac OS X Lion 10.7.3. When I try to download the update manually from Apple on my older iMac, it downloads okay, but when I try to open the dmg file, I get a warning message saying that opening this update may make your computer LESS secure. Do you want to proceed? (I did not).
Why would Software Update find this update and install it automatically on one iMac and not the other, if they are both running the same version of Mac OS X Lion? I checked the installed software list on my old iMac and the Java update does not appear there. Why would this update make my old iMac less secure?

Recall that Java is not installed as part of Lion.
You have to install it (and are asked if you want to) when you first try to run some java stuff.
Is it possible that the iMac 2007 does not have Java yet?
Try this: open Terminal (from Utilities) and type java -version (exactly like that, with the space before the hyphen).
What do you get?
Consistent with this theory is that the dmg thing gave you the warning - installing java might make your machine less secure because java is a means for bad guys to try to do bad things to your computer.

HT201232 My operating system is Mac OS X 10.6.8 and when I'm surfing the web, it tells me I need to update my browser however when I check for updates, nothing comes up. What do I need to do to get Mac OS X Lion v10.7?

My operating system is Mac OS X 10.6.8 and when I'm surfing the web, it tells me I need to update my browser however when I check for updates, nothing comes up. What do I need to do to get Mac OS X Lion v10.7?

Software update will only bring you up to the current level of the system you are using - you are at the maximum for Snow Leopard. To get Lion or higher you will have to go to the Mac App Store in Applications and purchase it there (Yosemite is free). You will need to check that your Mac meets the requirements and you should particularly note that PPC programs such as AppleWorks will not run in Lion or above.
The requirements for Lion are:
Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
2GB of memory
OS X v10.6.6 or later (v10.6.8 recommended)
7GB of available space
Lion is available in the Online Apple Store ($19.99). Mountain Lion (10.8.x) is also available there at the same price (though it's reported to have been removed from sale in some countries so may well cease to be available generally) but there seems little point as the system requirements are the same for Yosemite (10.10.x) - which is free - unless you need to run specific software which will run on Mountain Lion only.
The requirements for Mountain Lion and Yosemite are:
OS X v10.6.8 or later
2GB of memory
8GB of available space
and the supported models are:
iMac (Mid 2007 or newer)
MacBook (Late 2008 Aluminum, or Early 2009 or newer)
MacBook Pro (Mid/Late 2007 or newer)
Xserve (Early 2009)
MacBook Air (Late 2008 or newer)
Mac mini (Early 2009 or newer)
Mac Pro (Early 2008 or newer)
Yosemite is available from the Mac App Store (in Applications). Mountain Lion can be obtained the Online Apple Store. (Mavericks is no longer available.)
If the problem is only with Safari and you are otherwise happy with Snow Leopard you could switch to FireFox (free) - the latest version of that will run in Snow Leopard.

Mac OS X Lion donesn't start after Windows 8 installing

I'm having some troubles booting from Mac OS X Lion after installing Windows 8 Release Preview on bootcamp partition.
I've made these steps.
Install Windows 8 Consumer Preview using bootcamp
Upgrade Windows 8 Consumer Preview to Release Preview
Reboot the system and hold option key.
On bootcamp select Machintosh HD
Mac OS X Lion doesn't start, or after a lot of time, it presents me the accounts screen but I cannot select anyone, trackpad or keyboard doesn't works!
I tried to boot from Recovery HD, but keyboard and trackpack doesn't work too.
I tried to boot from Snow Leopard installation CD, but it also doesn't work.
If I restart and boot in Windows 8, everything works fine!
I have a Macbook Pro 15".
Could someone helps me?

Take a look at the partitions on the drive.
What is there?
When you do what you did it keeps 20GB Windows.old which you can delete after, and if the upgrade fails on Windows 8 CP you are left with Windows you had, and 20GB Windows.install temp file
So whatever you do using your method you needed to have 30GB of free space or more to perform the change.
And you should have a clone or backup of both that you can restore if needed.
Carbon Copy Cloner for instance to make an image of Lion and Lion Recovery.
WinClone 3.x to image Windows - though may not need to.
Windows Easy Transfer to make it quick and easy and act like it was an upgrade with all your settings (but not all programs and 3rd party).
Did you download the ISO also and burn to DVD? The download assistant for 8 will assist with that and then you can use Windows 8 DVD for system recovery.
Not a mind reader could know what the state of your system is now and if OS X is there or got clobbered.
Zap PRAM and try to boot from one of your DVD systems. (there are no CDs anymore they don't fit)

please get back to me and it says on the apple website i would be able to get it

I would make sure it's deffinetely a mid 2007, and that's not just when you purchased it. Also you need at least 2GB of RAM and an intel core 2 duo processor with 8GB of HD space.

Problems with Premiere Elements 9.0.1 on Mac OS X Lion

Hi,
I recently upgraded to Mac OS X Lion and I am having several stability issues with Premiere Elements 9.0.1 now. None of these issues occurred on Snow Leopard. I experienced these issues on a machine that was upgraded from Snow Leopard to Lion after Premier Elements 9.0.1 was installed and I also had problems with a Premiere Elements installation on a clean install of OS X Lion.
I noticed the following issues:
1) System hangs when trying to save a project. The "save" window stays open at 100% completion.
2) Nothing happens when dragging footage to sceneline. The clips do show up on the timeline, though
3) System crashed when trying to upload a video to YouTube
Could you please get these issues fixed and provide a patch for Premiere Elements?
Thanks.
Ralph

Mac OS X Lion Issues

I have recently bought and installed Mac OS X Lion on to my iMac, the issues I have been having is mainly to do with speed, my mac does not seem as quick as it used to be with Snow Leopard. This mainly happens when opening mission control to switch to other windows and apps, and then especially when opening launchpad. Another issue is when I go onto an application like Skype it seems to really lag when making a video call, although this issue had never happened in Snow Leopard. I have tried repairing permissions in Disk Utility, updating all of my apps and freeing up some hard disk space, yet nothing has really seemed to help with these issues.
The specs of my iMac is:
2.4 GHz Intel Core 2 Duo
4 GB 800 MHz DDR2 SDRAM
ATI Radeon HD 2400 XT 128 MB
20 Inch Monitor
250 GB HDD
This is also the early 2008 model of the iMac.
Any help with getting my mac running at normal speeds would be great!
Thanks!

I have a MacPro (2007), a MacBook Air (2010), an iPad2, and two iPhones. All have been updated to the current versions of their respective OS's. Everything is working very well. I could not be happier. iCloud is much improved over MobileMe as just one example.
Maybe its the 6 gigs of ram in the MacPro or the 4 gigs of ram in the MacBook Air. Maybe all you guys are short on memory.
Thanks Apple!
