600 isn't horrible, compared to 1500.
go in terminal and do:
ping skyblock.net

 

I did traceroute and ping, and it was roughly 40ms.

 

then it's something to with norton or something wanting mc to die.

 

I don't have norton or any protection like those types
These are the only applications open right now:

 

Obviously you are having packet loss
But it's only on mc servers?

 

Only MC servers. No other game, and no other website.

 

do you download resource packs and stuff

 

yea, I have like 4 of those and some hacked clients

 

some of your hacked clients could have malware

 

and since you don't have any anti-virus, of course a MAC wouldn't notice it

every time you open your minecraft whether its a hacked version or not, it could be causing you packet loss every time you join a server, which in result ends up in a higher latency

 

How do I access minecraft files?!11/!/1/!/?!?/

Just kidding, I'll delete them now

 

you go to DownloadMoreRAM.com - CloudRAM 2.0

 

dude did you download more ram yet
it made my pong 0.001

 

I have like 12GB of RAM mate I don't need more thx tho

Also, it didn't work. ;s
Should I delete all of the Minecraft files except the screenshots (I need)?

 

move the screenshots to somewhere else

 

This is a guess, but as soon as you click skyblock a couple seconds later does it just disconnect you?

 

read the damn op

 

It deleted like 5,190 files lol
I'll redownload MC now

 

is it better now
