Greek/math symbols do not display in Lion though working correctly in Snow Leopard.
I am attempting to edit/use powerpoint presentations created in Office 2011 on Snow Leopard. Though my math and Greek symbols display perfectly correctly on my Snow Leopard laptop, they do not display on my Lion desktop. Instead, they are replaced with a "W in a box" symbol. I have already been in the FontBook to resolve fonts as suggested on other discussions and this has had no effect. Right now my only solution appears to be to painstakingly replace every single symbol by hand using the "insert symbol" menu, whereas previously I could for example type "D" and then switch the font to "Symbol" to obtain a delta character. It appears to be a font issue with Lion: how do I get the proper symbol font back?
I appreciate any advice!
It is really a bad idea to use the old symbol font that lets you type D to get a greek letter. Instead you should be using Unicode fonts where you input math and greek via the Character Palette or a dedicated Greek keyboard layout.
But I gather that you have to deal with files that were created with the old stuff, and it sounds like your Lion machine is missing the old kind of font. Presumably you have one on your Snow Leopard machine, so you just have to move a copy to the Lion system.

Raidsonic NAS IB-4210-B is not accessible after Lion upgrade. Downgrade to Snow Leopard?
Hi, I'm in the same trouble as lots of others after upgrading to Liion. I have one Buffalo Terastation Life (works obviously fine 'til now) and two Raidsonic ICY-Box IB-4210-B I can see the shared folders but didn't manage to get access to them.
Any ideas others than downgrading to Snow Leopard?

I have a 2009 iMac and a mid 2007 Macbook. I also have an HTPC running Windows 7. I can connect fine to the HTPC from either the iMac or the Macbook, however, I am completely unable to connect to my Macbook or iMac from my PC. This was never a problem prior to upgrading to Lion from Snow Leopard. Please be advised that I know how to set my network up and have tried everything possible. I upgraded my iMac to Lion first and noticed the problem. After checking my settings I was stumped. I noticed that my PC could still connect to my Macbook running Snow Leopard. I then, today, installed Lion on my Macbook and replicated the problem I was experiencing on my iMac. Any suggestions?
The same happens to me!!! Any help out there?

Colorsync Engine is still not working correct in Snow Leopard 10.6.4
Colorsync Engine in 10.6.4 causes Print faults in Photoshop CS5.
A light cyan tone is being printed around pictures, where there should be plain paperwite.
I really would appreciate some help.
The problem shows when using custom paper profiles.
(The only situation, in which the problem does not show:
If sRGB is chosen as the printerprofile or if the paperprofile is chosen that belongs to the mediatype chosen in the Epson printersetting. Both are no options as they do not allow to print a colourmanaged print)
So it is obvious that there is still something wrong in the way the different profiles are matched....I am no beginner - you can believe this.
No insult meant at all. Just no way of knowing how much you do know on the subject.
I have custom paper profiles written for all my papers for this one printer Epson 4800 from targets I printed with no colour management from the printer driver and no colour profile tagged.
No problem there. That is the correct way to print the color patches for profiling.
There is no reason within the paperprofile to make the sourrounding area of the picture to be printed white...
In a very technical sense, there is. All profiles are built to include the ability to choose any rendering intent. So the option for Absolute Colorimetric is in there. Which leads to...
And besides that: How could a profile make an area be printed with a cyan tone that is around the image that is printed. In relative colorimetric rendering. How can you explain this?
It was just a thought. It wasn't until after I mentioned the possibility of using Absolute Colorimetric that you noted you always use Relative Colorimetric.
And the profiles worked before - under 10.5.8.
And they should in Snow Leopard. I'm using all of the printer profiles I made in Leopard for both an Epson Stylus Pro 4000 and a Xerox 6280DN in Snow Leopard. Color is identical from the same applications and the same test images. Both CMYK and RGB. I was able to easily test this as I have both 10.5.x and 10.6.x installed on two drives of the same Mac. So it was just a matter of booting into one, printing the images, then the other to do the same and compare output.
You noted at Adobe's forum:
Around the document, the printable space is filled with a very light colour.
Then printed it 5 to 6 times on the same sheet so it would be easier to see the cyan tone being printed. How was this tone added? I ask because your screen shot shows pure white as the background color. Is it neutral? Such as an RGB value of 253, 253, 253? If everything is correct (settings, profile, etc.), it should build up as a slowly darkening gray, not cyan. But you already know that.
But even if you choose no colour management in the printer driver, there are profiles and media settings that belong to the media you choose in the printer driver.
Not quite sure what you mean there. If you choose no color management, then any profiles in the printer driver are disabled. As far as the media settings, the paper you choose tells the printer the weight of the media going through it, so it can adjust the height of the guide tray. Important for heavy stock (canvas in particular) so it doesn't rub while going through. But much more importantly, it tells the printer how much ink to use. Plain paper will cause the printer to use a different amount of ink than if you choose something like Premium Glossy, even though both may be set to use a print quality setting of 2880 dpi.
The point there is that it is equally important to choose the exact same paper settings in the print driver as were used when the targets were printed, even though color management is turned off.
Actually, the issue may be how old these profiles are. I never print straight to the Epson 4000 since a profile can't account for drift. I go through the full version of the ColorBurst RIP for everything. The reason why is so you can account for hardware drift by re-linearizing when you notice grays starting to go pink/green/blue, etc. All inkjet printers drift as they are used. Meaning, the size of the dots change as the heads and ink pumps wear out. It's slow, but it does shift the color slightly as time goes by. Linearizing brings the gray balance and gamut back to its original point without having to create an entirely new profile.
A straight profile can't account for this. As the printer's color shifts, the profile can't move with it and colors shifts on your output starts to become apparent. -
Home computer is Lion, Work computer is Snow Leopard
My home computer is Lion, my work computer is Snow Leopard. My work computer needs to stay Snow Leopard becuase of a major program which runs the presspress department is not supported with Lion yet - so I cannot upgrade yet. I also jsut got an iPhone and want to use iCloud so that all three of those two computers and my iPhone sync together.
So, if I use iCloud for my home and my iPhone, what does that do to my work computer running Snow Leopard? Can I still get my mail just like I always do through "Mail" at work? I guess I just need to know what will change for my work (Snow Leopard) iMac?You do not lose your mail account when MobileMe terminates in June. However, when you move to iCloud you will not be able to sync your calendar or contacts with the Snow Leopard computer. You may want to read the following:

Strange scenario,Oracle can not display the data in mysql correctly
I use Heterogeneous Service+ODBC to achieve "oracle access mysql"(any other method?),and now i find Oracle can not display the data in mysql correctly:
-------mysql------------
mysql> create table tst(id int,name varchar(10));
Query OK, 0 rows affected (0.00 sec)
mysql> insert into tst values(1,'a');
Query OK, 1 row affected (0.00 sec)
mysql> select * from tst;
------------+

| 1 | a |

1 row in set (0.00 sec)

Table: tst
Create Table: CREATE TABLE `tst` (
`id` int(11) DEFAULT NULL,
`name` varchar(10) DEFAULT NULL
) ENGINE=MyISAM DEFAULT CHARSET=utf8
1 row in set (0.00 sec)
-------------oracle ------------------
SQL> select count(*) from "tst"@mysql;
COUNT(*)
49
SQL> select * from "tst"@mysql;
id
1
SQL> desc "tst"@mysql;
Name Null? Type
id NUMBER(10)You can make the following query on the result page:
"select * from the_table where movietitle = ? and cinema = ?"
then you set movietitle and cinema to those which the user selected. If the resultset contains more than 0 rows, that means the movie is available.
Below is the sample code, it assumes you have a connection to the database:
PreparedStatement stat = myConnection.prepareStatement("select * from the_table where movietitle = ? and cinema = ?");
stat.setString(1, usersMovieTitleSelection);
stat.setString(2, usersCinemaSelection);
ResultSet res = stat.executeQuery();
if (res.next()) {
out.print("The movie is available");
} else {
out.print("The movie is not available");
}Now just add that to your JSP page. Enjoy ! =) -

rashadDoes a method in your PicMsgComposer silently catch an exception and returns
an empty array or null?
That what the trace looks like.
The real problem might be an AccessControlException thrown by checkPermission or
a class that is not found (classpath) or something else. -
My MacBook Pro, 1.83 GHz Intel Core Duo gives me an error message during Lion install. My Intel Duo Core is not an Intel Duo Core and cannot install Lion. I already have Snow Leopard what is the problem with Lion?
You need a "Core 2 Duo" for lion, and I'm guessing you only have a "Core Duo" My wife's macbook is also a "Core Duo" and has Snow Leapord, but cannot install Lion.....

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.

I had Leopard on may Mac. I upgraded to Mountain Lion using Snow Leopard. I can't use my video with Mountain Lion. Can I load Snow Leopard on an external hard drive so I can use it with my camera?
First, you cannot do this if you have a Boot Camp partition.
Second: Create a new partition.
1. Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
After the main menu appears select Disk Utility and click on the Continue button. Select the hard drive's main entry then click on the Partition tab in the DU main window.
2. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed. (Note: You can only make a partition smaller in order to create new free space.)
4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
You should now have a new volume on the drive.
It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss. Your drive must have sufficient contiguous free space for this process to work.
Third: Install Snow Leopard.
Boot from your Snow Leopard DVD. Follow instructions for installation being sure that before you actually install Snow Leopard you have selected the new partition as your target destination.
Booting From An OS X Installer Disc
1. Insert OS X Installer Disc into the optical drive.
2. Restart the computer.
3. Immediately after the chime press and hold down the "C" key.
4. Release the key when the spinning gear below the dark gray Apple logo
appears.
5. Wait for installer to finish loading. -
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?
Maybe you are looking for
