program  in running ? i'm using 10.1.4

VLC player 

vlc player is the best already.

Hey bro, how's the rose gold looks like? Acceptable?

just move or copy it to the application folder.

Wow just got my MacBook collected !

What is the battery cycle number that come with the MacBook when you first boot up?

few second different nia m5 vs m7

So unless you are using Final Cut Pro, otherwise better get m5 lo?

M3 - rm5289, m5 - rm6489, m7 512gb - rm7110, m7 256gb -rm6342

M3 to m7 - rm1035, m5 to m7 - rm621
So it means m3 to m5 is only rm414.

M3 and m5 model price difference - rm1200

Rm1200 - rm414 = rm786 (256 extra ssd)

M7 512gb vs m7 256gb = rm768 extra (256 extra ssd) which it is very consistent to rm786 for m5 model.
so extra 256gb extra storage price is around there.

actually buying m5 model majority of price difference paid goes to the ssd.

Since m5 most price difference is for the ssd, the rm414 is actually very minimal comparing to the extra speed boost for turbo boost 2.7GHz vs 2.2GHz.

I had installed windows 10 on boot camp. I allocate 128gb to is x while the rest goes to bootcamp for my 512gb hardisk. I would say that for serious work user, 256gb can be very little in long run.

hohoho rose gold really not bad

1. You can create permission by right clicking the folder > Get info > Sharing & Permission
2. Click on Finder > Preferences > Advanced > uncheck Show all filename extensions
3. Go to System Preferences > Internet Accounts and set up your mail there. (Not very sure if you mean this)
4. Go to System Preference > Mouse and adjust the speed there
5. I don't know. I haven't restarted my MBP since last year.

Then I think you will have to manually hide the file extensions yourself:
Right click to Get Info > Name and extensions > Check Hide extension

I really not sure what happened to your mail. I'm using gmail as my apple ID and I can log into both iCloud and Gmail separately.
Try remove everything and redo:
After you have added your iCloud, add your hotmail account by adding under "Mail account"...
(Alternatively is to login as xxx@icloud.com instead of xxx@hotmail.com when you setting up your iCloud account)

Should not be a problem as your xxx@icloud.com is the same account as your xxx@hotmail.com under iCloud. They are the same Apple ID.

anyone notices lag while scrolling through the web page on web browsers?

You do not need to anymore. Just set up keychain and everything will be automatically available (including your email settings, passwords) once you have logged into your iCloud account in your other Apple devices in the future.
Please do not confuse yourself. You are not using an email ID/Apple ID to log into your MacBook. The username for login your MacBook works only locally in your MacBook and have nothing to do with your Apple ID/email ID.
In case you want to find out, just go to System Preferences > Users & Groups
You can also change your login settings there.
