I decided not to use the report format because the amount of tests made and results returned. I will include details and my own comment for each test.
Launcher Version: 1.0.1.3
LWJGL Version: 2.8.3
Test 1
Operating System: Mac OS X 10.6.8
Mod Pack: Technic 7.0.1
Java Version: Java 6 SE from Apple (VM: 1.6.0_31-b04)
I opened the launcher on my MacBook which was running Snow Leopard to try play technic but then it caused an error which was obviously caused by not using JDK7.
I then proceeded to play it on my Mac Mini which was running Lion, turned on OpenJDK7(I don't usually use OpenJDK7, the version I installed at that time was a DP version of it.) then opened the launcher. I started Technic but the game window froze on a white screen, I tried the methods supplied in the common problems thread but it failed every time I tried to launch.

I peeked at the logs and found out it was a problem with the libraries. I went to the bin/natvies/ folder and found out that there was no such file called "liblwjgl.dylib" but instead I found another file called "liblwjgl.jnilib". At first I suspected the file to be outdated but then after I downloaded the latest lwjgl binaries, I found "liblwjgl.jnilib" but no "liblwjgl.dylib". I found a thread with the same problem and tried the suggested solution: duplicating the file and renaming it to "liblwjgl.dylib". I did but Technic crashed on load, no errors were generated. (Note: the library could have loaded but some unknown reasons caused it to crash)
Test 3
Operating System: Mac OS X 10.7.3
Mod Pack: Technic 7.0.1
Java Version: Java 7 SE (VM: 1.7.0_04-b21) & Java 7 SE (VM: 1.7.0_06-ea-b08)
I found out on the internet that the problem apparently was a missed out feature, not implemented in my version of release.* I then downloaded the Oracle release of JDK7u4, installed it, then launched Technic, it crashed on load, no errors. This was the same with JDK7u6 DP. I even tried it on a newer build of JDK7u4. (maybe the library did load but somehow caused it to crash.)
At this point I was frustrated, but then I read that it was first fixed in JDK8.** I installed it then it crashed on the launcher. It generated an error report but it said the crash was caused by Java. (I will attach it someone wants it)
Test 5~ (for comparison only)
Operating System: Mac OS X 10.7.3
Mod Pack: VoxelModPack
Java Version: Java 7 SE (VM: 1.7.0_06-ea-b08)
I then proceed to test if other modpacks (voxelmodpack in this case) have the same problem. It does on JDK7.
Java Version: Java 6 SE from Apple (VM: 1.6.0_31-b04)
Tried it with Java 6 and it works, the voxelmodpack does not require JDK7 so it works. (not sure if lwjgl loaded)
Operating System: Mac OS X 10.6.8
Java Version: Java 6 SE from Apple (VM: 1.6.0_31-b04)
Tried it on Snow Leopard, works. (not sure if lwjgl loaded)
Operating System: Mac OS X 10.7.3
Mod Pack: None. Completely vanilla minecraft. (Minecraft launcher)
Java Version: Java 7 SE (VM: 1.7.0_06-ea-b08)
Works without error.

Some questions answered for mac users
Will modpacks requiring JDK7 be able to run on Snow Leopard or older?
No. Mac OS X 10.7.3 (Lion)† is listed as a requirement and it the only supported platform by Oracle. ‡
Why is the game stuck on a white screen?
The game cannot load the lwjgl libraries. Update Java if using Java 7 or use Java 6.
Why does the game immediately crashes on load? (Before the Mojang logo loads)
This is caused either by a mod, a modpack, lwjgl. No solution or explanation to this currently.

* (Technical Discussion) In the JDK7 Mac Port Project Status Page it states (Core Libraries) that in 7u4 you are able to load .jnilib in addition to .dynlib
** (Technical Discussion) Please correct me if I'm wrong
*** I have programming experience, but none for Java. All comments are based on my current knowledge of computers and programming.
† Purchase Lion 64-bit computer required
‡ As stated in the JDK7 Mac OS X Port Wikis
