The former Shamrock Rovers boss was confirmed as Nigel Worthington's successor by the Irish Football Association on Wednesday, beating Jim Magilton and Iain Dowie to the job, and will start work on February 1.
O'Neill played as a midfielder or forward for Chimney Corner, Coleraine, Newcastle, Dundee United, Hibs, Coventry City, Aberdeen (on loan), Reading (on loan), Wigan, St Johnstone, Portland Timbers, Clydebank, Glentoran and Ayr United.
While at Newcastle in the 1987-1988 season he was the clubs top goal scorer with 12 goals in the top flight of English Football, playing alongside Paul Gascoigne amongst others.
Between 1987–1989 he made 48 appearances for Newcastle United scoring 15 goals.
Worthington's four-and-a-half-year reign ended in disappointment with a fifth-placed finish in their Euro 2012 qualifying group, while a record of one win in their last 13 fixtures - a home success against the Faroe Islands - made for grim reading.
The former Norwich boss was subjected to some fierce criticism from the stands in his last few matches at the helm, with sections of the fans regularly calling for his sacking.
Now McAllister, chairman of the Amalgamation of Northern Ireland Supporters' Clubs, wants everybody to get behind the new appointment.
Gary McAllister: "I think the relationship with the manager over the last year was at a very low ebb, but we need to look forward not keep looking back.
"As fans we've not had too much to celebrate in the last year but now is time to look forward. We all need to get behind Michael O'Neill.
"A new manager can create a new dawn, if you will. There's always a little sparkle and people are hopeful that it can lead to something good or a repeat of past glories.
"We have to realise we have lost a lot of players and we're entering a period of transition with a new manager but hopefully it can be successful.
"The main thing is he needs to be given time."
O'Neill performed admirably in his time at Shamrock, winning back-to-back League of Ireland titles and creating history by leading the club into the group stages of the Europa League, but his CV lacks the top job in England or Scotland that many felt would be a necessary requirement.
Dowie's Barclays Premier League experience (including a spell at Newcastle under Alan Shearer) and Magilton's time at Ipswich and QPR gave them the edge in that regard, but the IFA were won over by O'Neill's interview.
