My iMac has recently been hacked into and I'd like to make it more secure by preventing incoming connections from hackers.

Feb 11, 2018  I got little snitch for just this reason. I block everything until I look it up, auto deny everything go back and fix later. Do a Whois on the domain name that's trying to open and do a trace route or even search for the site on google and see what you find. You can usually get a. Feb 28, 2018  For me the last seven are trusted items in that I know what they belong to (Java update info to run Adobe products, some Adobe stuff itself, the Little Snitch install and an item to do with my Printer) There is one item there though that does refer back to when this Mac User Account was migrated from a G4 computer. May 27, 2013  Simply put, a successful install using this method is full proof and will result in EVERYTHING working (i.e. Repair permissions, the ability to install apple system updates and for that matter any other application including Little Snitch, iMessage, FaceTime. Auto-tune access by antares. ICloud just as you would normally, full native 64 bit mode available at your disposal. Hackintosh is your only solution but iMessage won't work, and you'll always be on the hook for support. All the features of iCloud/iOS that work with OS X need a recent if not the most recent version of OS X. Any help with this is greatly received. I have a Catalina Build and uninstalled Little Snitch (stopped Little Snitch first) on. ICloud Issue After El Capitan Update 10.11.2. Ask Question Asked 4 years, 1 month ago. Deleted Keychain entries for imessage and com.apple.idms. I thought about that, as I have used Hands Off, and Little Snitch in the past, but neither were installed on my device at the time.

Jan 20, 2018  Still, your Mac's standard firewall allows for these unlikely connections, but a customized Intego ISB X6 firewall (a 3rd-party firewall for Macs that run anything at, or newer, than the Leopard Operating System) will block them.

Using the latest tool. Everything works well except when I run the latest Little Snitch nightly, the Little Snitch daemon uses up pretty much all my CPU. I've tried force rebuilding cache, the sudo kextcache, reinstalled Little.


I'm not sure how I should setup the rules for this purpose.
Would all protocols and ports be concerned?
By default, LS allows all system and non-system incoming connections via UDP, ICMP and local network. Is that safe?
I have disabled WiFi and am connected via an Ethernet cable to my router. There is no other computer in my local network. I'm also running the Mac firewall.
Ideally, I'd like to be alerted when there is an intrusion attempt, i.e. when an incoming connection is attempted. I'd like to know the source. Is that possible with LS?
Thank you for your help.

Hi everyone,
I was wondering if someone could explain the protected rules at the top of the LS configuration, and why I would enable or disable them?
What are ICMP/UDP incoming connections? I know the right hand side of the LS configuration provides a little explanation for both, but I would like some more information on it. Would my internet experience suffer if I were to disable them? What's the risk, in terms of malware/remote access, if I kept them enabled?Imessage

Also - allowing outgoing or incoming connections to my local network - why would I or wouldn't I need to do that? Does it open me up to infecting my system if other machines on the network are infected (especially if I'm using public wi-fi)? I'm on the home wi-fi and I tried testing it out just then by disabling the incoming connections from local network rule. Within 5 minutes LS notified me that my Macbook (system, not me) tried to establish incoming connections to mDNSResponder, port 5353:
- from the IPv4 address associated with my Macbook on the home wifi
- from fe##::####:#$$$:$$$#:##$$

I feel comfortable using LS but my knowledge of networking/IP stuff is basic at best, so I need some assistance in understanding the protected rules.
